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.
