has no event, but where its queue's wakeMask is also reset
to zero. Reentering TASK_Reschedule in this state would be
suicide. Hence, we do return to the caller after processing
non-hardware events. Actually, this should not hurt anyone,
as the caller must be WaitEvent, and thus the QUEUE_WaitBits
loop in USER. Should there actually be no message pending
for this task after processing non-hardware events, that loop
