:If the kernel is going to automatically complete KSEs, then I would only
:do it when new KSEs block or when the process is resumed. The UTS is timing
:the current thread, so you don't want to do work for other threads while
:the UTS is going to count it against the currently running thread. If the
:kernel is not automatically completing the KSEs, then the UTS can be notified
:of unblocked KSEs at any time.
The kernel *must* complete blocked KSE's or you run into a thousand
potential system deadlock situations. We have no choice there.
:... interesting stuff (removed) ...
