Is there an accepted order for shutting down these "services"?
I know they have a "Shutdown handler",  but there are no examples
on how to use it....   Shouldn't that eventually be written into the
WIKI?

It was much much easier for me to deploy a "state" variable
to tell me what State the stack is in,  so I can deploy the proper
shutdown code.  Seems to work for me,  and I intend to do it this
way until an easier way is found.
