Hmm -- I would jump right on this if I knew how to go about it. I'm not much
of a C/C++ programmer.

I've done some googling about POSIX semaphores on OS X, and found some
interesting things in Mac OS X developer documentation. It looks like OS X
has some wrapper functions built in to account for its apparently incomplete
POSIX semaphore implementation.

Thanks for the pointer!
