Comment (by simonmar):
This does look like a step in the right direction. How does this compare
in performance to the select version? Glancing at the patch it looks like
building the fdset will be more expensive than before. There's one
withForeignPtr per FD. The INLINEs on the C functions don't have any
effect (unfortunately), even with `-fvia-C`.
