that's yucky. there's a fairly well-established body of work
including Mach Scheduler Activations (Bershad, I think) for
doing this much nicer. rather than forcing the app to fantically
poll the kernel to keep its threads running, SA's let the kernel
notify the thread manager when a thread blocks...
