If I understand correctly what you suggest, it does not fit what I want.

Now, it doesn't happen, and I'm not sure why it ever would, but the 
listener might have to go down for some reason.  This would kill all 
threaded processing, sub-processes, and such.  My desire is to spawn the 
worker processes, and they would then be independent of the listener. 
While most jobs run very quickly, what about a request for a report that 
takes 3 hours to run and then return the result(s)?

I learned long ago that when someone tells me "that never happens", it 
will be one of the first things to bite me on the ass, and therefore I 
plan for it happening.
