Yes, but if SvcStop is called, SvcDoRun should also finish 
afterwards...one can see the "DONE"
being printed when stopping the service with the service manager, but 
not when rebooting the machine.
Adding a print statement in in SvcStop (as the first thing it does), 
also doesn't get me any output...
To me it looks like it really just is not being called.
