Are you doing anything with threading (I see you are making a call to pythoncom.GetInterfaceCount()? If so check out
http://stackoverflow.com/questions/16367328/memory-leak-in-threaded-com-object-with-python/16617092#16617092 I've had an issues with a leak and win32 and this took care of it. I have had a couple other problems with win32 and memory leaks and eventually I just throw the code execution in a separate python.exe process using multiprocessing so that the entire memory space is isolated and released when I end that process. Not very clean, but it works.
