Threaded RTS problems on Solaris

[simonmar]

Just so we don't forget: the threaded RTS also has problems on Solaris, both Sparc and x86 have been reported to have problems. The symptom is that the stage2 linked with -threaded crashes at random points.

Might be related to #751.

Now appears to be fixed by this:

    ghc/rts              Capability.c 
  Log:
  Fix crash in the threaded RTS caused by spurious wakeups of
  pthread_cond_wait().  This is certainly affecting the threaded RTS in
  6.4.x on Solaris, and possibly other platforms too.  I'm currently
  testing to see whether there are any further problems on Solaris, but
  with luck this may be the final fix for the threaded RTS problems in
  the 6.4.x branch.
  
  Does not affect 6.6; the corresponding code in 6.6 is already
  spurious-wakeup-safe.
