[Prevent duplication of unsafePerformIO on a multiprocessor
Simon Marlow <simonmar@microsoft.com>**20070306145424
 Fixes #986.  The idea is to add a new operation
 
   noDuplicate :: IO ()
 
 it is guaranteed that if two threads have executed noDuplicate, then
 they are not duplicating any computation.
 
 We now provide two new unsafe operations:
 
 unsafeDupablePerformIO    :: IO a -> a
 unsafeDupableInterleaveIO :: IO a -> IO a
 
 which are equivalent to the old unsafePerformIO and unsafeInterleaveIO
 respectively.  The new versions of these functions are defined as:
 
 unsafePerformIO    m = unsafeDupablePerformIO (noDuplicate >> m)
 unsafeInterleaveIO m = unsafeDupableInterleaveIO (noDuplicate >> m)

[document timeout limitations
Peter Simons <simons@cryp.to>**20070228223540] 
[So many people were involved in the writing of this module that
Peter Simons <simons@cryp.to>**20070228223415
 it feels unfair to single anyone out as the lone copyright
 holder.
] 
[This patch adds a timeout function to the base libraries. Trac #980 is
Peter Simons <simons@cryp.to>**20070126222615
 concerned with this issue. The design guideline for this implementation
 is that 'timeout N E' should behave exactly the same as E as long as E
 doesn't time out. In our implementation, this means that E has the same
 myThreadId it would have without the timeout wrapper. Any exception E
 might throw cancels the timeout and propagates further up. It also
 possible for E to receive exceptions thrown to it by another thread.

     forM_ :: (Monad m) => [a] -> (a -> m b) -> m ()

[Change the API of MArray to allow resizable arrays
Simon Marlow <simonmar@microsoft.com>**20060809100548
 See #704
 
 The MArray class doesn't currently allow a mutable array to change its
 size, because of the pure function 
 
   bounds :: (HasBounds a, Ix i) => a i e -> (i,i)
 
 This patch removes the HasBounds class, and adds
 
   getBounds :: (MArray a e m, Ix i) => a i e -> m (i,i)
 
 to the MArray class, and
 
   bounds :: (IArray a e, Ix i) => a i e -> (i,i)
 
 to the IArray class.
 
 The reason that bounds had to be incorporated into the IArray class is
 because I couldn't make DiffArray work without doing this.  DiffArray
 acts as a layer converting an MArray into an IArray, and there was no
 way (that I could find) to define an instance of HasBounds for
 DiffArray.

       if we compare that to unfoldr:
       unfoldr :: (b -> Maybe (a, b)) -> b -> [a]
       
       So we can generalise unfoldrN to this type:
       unfoldrN :: Int -> (a -> Maybe (Word8, a)) -> a -> ByteString
       
       and something similar for the .Char8 version. If people really do want to
       use it a lot with Word8/Char then perhaps we should add a specialise pragma.

 The stricteness analyser used to have a HACK which ensured that NOINLNE things

 the strictness analyser would discover this strictness for unsafePerformIO:

 But then consider this sub-expression
        unsafePerformIO (\s -> let r = f x in

                               (# s1, r #)
 The strictness analyser will now find that r is sure to be eval'd,
 and may then hoist it out.  This makes tests/lib/should_run/memo002
 deadlock.
 
 Solving this by making all NOINLINE things have no strictness info is overkill.
 In particular, it's overkill for runST, which is perfectly respectable.
 Consider
        f x = runST (return x)
 This should be strict in x.
 
 So the new plan is to define unsafePerformIO using the 'lazy' combinator:
 
        unsafePerformIO (IO m) = lazy (case m realWorld# of (# _, r #) -> r)
 
 Remember, 'lazy' is a wired-in identity-function Id, of type a->a, which is 
 magically NON-STRICT, and is inlined after strictness analysis.  So
 unsafePerformIO will look non-strict, and that's what we want.

   * dcoutt's packByte bug squashed
   
   With inlinePerformIO, ghc head was compiling:
   
    packByte 255 `compare` packByte 127
   
   into roughly
   
    case mallocByteString 2 of
        ForeignPtr f internals ->
             case writeWord8OffAddr# f 0 255 of _ ->
             case writeWord8OffAddr# f 0 127 of _ ->
             case eqAddr# f f of

                                          (GHC.Prim.plusAddr# f 0)
   
   which is rather stunning. unsafePerformIO seems to prevent whatever
   magic inlining was leading to this. Only affected the head.

 after kind help from Roman Leshchinskiy, 
 
 Pipelines of maps, filters and folds should now need to walk the
 bytestring once only, and intermediate bytestrings won't be constructed.

 This patch brings Data.ByteString into sync with the FPS head.
 The most significant of which is the new Haskell counting sort.
 
 Changes:

   * Fix foldr1 in Data.ByteString and Data.ByteString.Char8
 
 Mon May  1 11:51:16 EST 2006  Don Stewart <dons@cse.unsw.edu.au>
   * Add group and groupBy. Suggested by conversation between sjanssen and petekaz on #haskell

   * Fix groupBy to match Data.List.groupBy.
 
 Wed May  3 15:01:07 EST 2006  sjanssen@cse.unl.edu
   * Migrate to counting sort.
   
   Data.ByteString.sort used C's qsort(), which is O(n log n).  The new algorithm 
   is O(n), and is faster for strings larger than approximately thirty bytes.  We
   also reduce our dependency on cbits!

[RequireOrder: do not collect unrecognised options after a non-opt
Simon Marlow <simonmar@microsoft.com>**20060426121110
 The documentation for RequireOrder says "no option processing after
 first non-option", so it doesn't seem right that we should process the
 rest of the arguments to collect the unrecognised ones.  Presumably
 the client wants to know about the unrecognised options up to the
 first non-option, and will be using a different option parser for the
 rest of the command line.
 
 eg. before:
 
 Prelude System.Console.GetOpt> getOpt' RequireOrder [] ["bar","--foo"]
 ([],["bar","--foo"],["--foo"],[])
 
 after:
 
 Prelude System.Console.GetOpt> getOpt' RequireOrder [] ["bar","--foo"]
 ([],["bar","--foo"],[],[])

 For some time, GHC has made -fallow-overlapping-instances "sticky": 
 any instance in a module compiled with -fallow-overlapping-instances
 can overlap when imported, regardless of whether the importing module
 allows overlap.  (If there is an overlap, both instances must come from
 modules thus compiled.)
 
 Instances in Data.Typeable might well want to be overlapped, so this
 commit adds the flag to Data.Typeable (with an explanatory comment)

 means expressions involving [n..m] aren't being completely optimised
 because eftIntFB isn't being inlined but otherwise the results look
 good.

 erroneously using take to duplicate work in a misguided attempt to
 lengthen their runtimes (ToDo).
