This is what GHC does, if I understand you correctly. The thread running select() does so in its own OS thread, while another OS thread runs the Haskell code. As long as you use -threaded, that is. Oh, and before GHC 6.4 it was done a different way - the scheduler used to do the select() between running Haskell threads.
Cheers, Simon
So this means even though the IO calls block, the other Haskell threads (when run with -threaded) keep running?
Yes, unless the IO is to/from disk on a Unix system. Cheers, Simon
