strange, but your letter don't contains crossposts to them. may be
it's because i had errors when tried to add crossposting to them.
well, i continue in the libraries list

i don't mentioned all the features that are already in ghc i/o
library, they are just too numerous. but of course i suppose that we
want to support them all. non-blocking i/o is among these things (see

async i/o is idea of SimonM/JohnM/Einar of adding support of epoll and
other async i/o systems so that thousands of haskell threads may
perform i/o simultaneously w/o much cpu overhead. btw, it's already
implemented in network-alt lib, but only for its networking i/o
facilities. John Meacham issued an idea of universal API on top of all
these systems that may be used by any i/o library (and haskell
compiler) to easily implement support for async i/o. but we need
details, unix tricks is not my area of knowledge

yes, it's one more topic that i lost (and what i don't understand like
i don't understand unix)
