4380	Use throwIO instead of throw in an IO context	basvandijk	simonmar	"Some functions in base use `throw` where the type of the expression is `IO`. I think they should be using `throwIO` since it guarantees ordering with respect to other IO actions.

See the [http://thread.gmane.org/gmane.comp.lang.haskell.libraries/13851 thread] on the libraries list.

Some simple benchmarks in the thread also showed that `throwIO` is faster than `throw`."	bug	closed	normal	7.0.2	libraries/base	6.12.3	fixed			Unknown/Multiple	Unknown/Multiple	None/Unknown
