As we now have a common ReferenceCounter class to use, I have converted
this
over to use ReferenceCounter to control the deletion. One reference is
made
on creation, and a second when it is added to the process map. The second
reference is decremented when the MythSystemSignalThread is done shutting
it
down cleanly.

NOTE: I may have missed some dependency on the parent item which may have
been deleted already. If this happens, please let me know. It would most
likely crash hard in this case. I'll take another look over it in a bit.

Refs #10775. Refs #10889.

Please retest with the latest. I think it should be fixed, and any
segfaults in that area now will need fixing for sure still.

I don't think it's related to the same crash, but it has crashed again
this morning.

Since this seems to be solved, closing. Can always be reopened if it
reoccurs.
