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. -- -Colin
