Description of problem:
The config tools are python clients talking to a single ruby agent that is managing numerous objects via the objects methods.  Sporadically, I see an exception being thrown from the qpid libraries when the tools finish executing:

Exception in thread Thread-1 (most likely raised during interpreter shutdown):
Traceback (most recent call last):
