Just FYI, even if it wouldn't have leaked forever, it caused me serious 
pain because it kept a reference to a COM object. The process wouldn't 
die until the object died and all of my usual techniques for breaking 
circular references were of no avail. I even tried nasty hacks like 
globals.clear() and self.__dict__.clear(). But there was no circular 
reference to be broken.
