<div> 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.e. the underlying OS APIs would be totally hidden. The reason I bring this up is that OS abstraction layers are very common in "mainstream" languages like C++. Any code written using an OS abstraction layer is absoutely portable. IMO if Haskell (or say OCaml) want to be accepted by industry this kind of functionality is absolutely critical.

<br><br>Most of the code is platform neutral. A few specific bits<br>(System.Posix, System.Win32) are limited to one operating system, but<br>that's hardly any of it. If you just write code, there is a strong<br>chance it will work perfectly on both operating systems. I've only
