/*
* Semaphore support.
*
* This implementation is ripped directly from the pthreads implementation.
* Which is to say that it is 100% non-functional at this time.
*
* Assuming the page is still up, documentation can be found at:
*
* http://www.doc.ic.ac.uk/~mac/manuals/solaris-manual-pages/solaris/usr/man/man2/_lwp_sema_wait.2.html
*
* Looking at the man page, it seems that one could easily implement a
* semaphore using a condition.
