Another quick test confirms that the following works:

    def __del__(self):
        try:
            print "Deleting", self.__module__, "module."
            del sys.modules[self.__module__]
        except Exception, e:
            print "Failed:"
            print e

Now every change I make to the module immediately gets picked up by the
shell extension. No more killing Explorer! Can you (or anyone) see any
problems with this?
