Is there something planed to happen in 2010?
Retooling the I/O manager isn't a huge job, but it requires the
equivalent of several weeks of work. I tossed out my initial attempt
at a patch because I didn't have time to work on it, so I'm back to
square one. Johan Tibell and I have had occasional discussions about
picking up the thread again, but we've had a busy year and it's
moderately demanding work, so nothing has actually happened.
If I develop the time and energy to take a serious crack at it, I will
post here to let people know. This would be an effort where having
multiple people work on different implementations concurrently would
be a shame.
Yes, this is definitely a vital point of the runtime which requires
carefull handling. I doubt that the estimated effort in
http://hackage.haskell.org/trac/ghc/ticket/635 reflects reality;)
However, factor (factorcode.org) implemented epoll, kqueue (for BSDs and
MacOS) and |GetQueuedCompletionStatus for Windows in 2008. In this case
the blog http://factor-language.blogspot.com/search?q=epoll and the irc
logs
http://www.google.com/search?q=epoll+site%3Atunes.org%2F~nef%2F%2Flogs%2Fconcatenative%2F&btnG=Search&hl=en&tbo=1&sa=2
might be helpful for a start and to avoid pitfals.

Johann
