-----------------------------+----------------------------------------------
I've written a patch for libraries/unix adding support for POSIX named
 semaphores and shared memory objects.  It's a straightforward wrapper
 around the POSIX system calls, basically just converting between C types
 and Haskell types and closing semaphores when they get garbage-collected.

 I don't plan to implement unnamed semaphores because Control.Concurrent
 already has perfectly good support for that.  Named semaphores, on the
 other hand, are for IPC, and there's no other alternative if that's what
 the process on the other end is expecting.

 The patch is here:
