[Haskell-beginners] Multiplexing I/O in Haskell

[Sergey V. Mikhanov]

   Hello community,

Is there a good/proper way to do multiplexing I/O in Haskell, similar
to what we are getting by using select()/poll() in Unix kernel? It
does not seem impossible to implement this on top of existing IO
library (though I haven't tried this actually, so I may be wrong).
What interest me most here is whether we could use Haskell's implicit
multithreading here (select()/poll() combination is all about
multithreading)?

Thanks in advance,
Sergey
