OK, I'm an idiot.  It had nothing to do with the reload script.  The 
connections were from the TestCase subclass I have that instantiates a 
connection management object.  It appears that the unittest module does 
not dispose of the objects it instantiates until the end of the run, so 
you need to REALLY clean up in the tearDown method.  I discovered this 
by making a persistent connection for the reload operation and noticing 
that the number of connections still increased.

Thanks to all who responded.
