Since the error is being raised in httplib, it would seem your web 
server is not responding correctly (bad status line).  I would try doing 
several test calls with just httplib (or urllib2) against this same URL 
and see if you can replicate the error.

Define "simple." :) I've used some pretty complex WSDL files, and it's 
never taken as long as a minute.  The Sax parser is pure python, so it 
might not be the fastest thing out there.  Also, look into the caching 
options.
