The problem appears to be in httplib.HTTPConnection.  I replaced
xmlrpclib.Transport with my own socket-based Transport and the memory
leak goes away.  So, I took the HTTPConnection sample out of the Python
doc and stuck a loop around it.  Sure enough, I see a 4K increase every
10 seconds or so over the life of the process.

Thanks,

Mark
