There could be OS limitations on the number of threads a process may
have. I was thinking about "user-scheduled" tasks, which are not
scheduled at all. Some user task explicitly releases one task from the
pool and gets control back when that task calls to an entry. The
important point I believe is preemption. "User-scheduled" tasks would
not be required to be preemptive.
