Memory leak in xmlrpclib.py on Windows?

Hi,

I'm running a very simple XML-RPC client/server on Windows 2000 using
Python 2.2.1.  Using perfmon, I see about a 4K increase in the size of
my client and server processes after about a half dozen or so calls.  It
doesn't seem to matter which parser I use (expat or SlowParser).  I get
similar results.  I also ran my test on a Linux box without expat and
did NOT see the leak.  Any ideas?  I seem to remember seeing something
about a leak in the expat parser, but, like I said, I see similar
results using the SlowParser.  I've attached my scripts if anyone would
like to try it.

Thanks!
