Bug 239050 I was finally able to get the cache working for the MIProcesses service. And for both non-stop and all-stop mode.

Browse source 
Basically, the cache of this service is used for container-level commands; therefore it should only be made unavailable/available on Container events.  In all-stop we issue container events, but not in non-stop.  So, everything works.

Furthermore, I only clear the cache when threads start and exit.
