In older Mach papers, I saw these two functions, or other names for them,
to increment the suspend count, and to sleep until the suspend count
was zero.  There were examples that showed the use of this split to user
semaphores.

In the 3.0 release, and some older, but not that old, papers, I can only
find thread_suspend, which subsumes both.

Does anyone know what happened?  I'm curious.
