I am really talking about a module or perhaps a Haskell class that provides notion for multiple threads of execution, semaphores, .. that "hides" POSIX vs Win32 APIs ..

I wonder if this discussion is missing the point: if you only want to do threads, then Haskell (or GHC, to be more precise) already provides thread abstractions that hide the OS-specific implementation details. In fact, doing it yourself with the FFI is likely to cause a lot of problems. Take a look at the Control.Concurrent module, and GHC's -threaded option. Cheers, Simon
