Yeah, Python is never 'finalized' when it is loaded for use by a COM object.

This should be reliable - assuming that the program *using* the COM object
always destroys the COM object correctly.  However, it would be possible to
write a Python program that used the COM object that did *not* cleanup the
object, so would not cause this method to be executed...
