[Haskell-cafe] OS Abstraction module??

Hi Neil,

    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

Kind regards, Bill
