SH-3184/SH-3221 More work on cleanup with better unit test work and more aggressive shutdown of a thread.

Some additional work let me enable a memory check for the clean shutdown case and
generally do a better job on other interfaces.  Request queue waiters now awake
on shutdown and don't sleep once the queue is turned off.  Much better semantically
for how this will be used.
