[Haskell-cafe] Poisx select support

[Galchin Vasili]

Hi Don,

     I am looking at the code for ghc-6.8.2 but don't see the mmap support.
Is this newly wriiten by you? I would also like to help round out the Posix
functionality in Haskell. Is there an accurate list of what needs to be done
given the fact that maybe some work is in progress but not "checked in"?

Thank you, Vasili
