I think using httplib to return session data is risk to put it mildly. I'd put money on the fact that it's either that or your ORacle query that's hanging...

What do the hung threads say they're doing on the debug info panel?

for example:
    * Connections:
    * Fri Sep 12 10:28:09 2003 (11650.65s) ({'HTTP_ACCEPT_ENCODING':
      'gzip,deflate,compress;q=0.9', 'SERVER_PORT': '8888',
'PATH_TRANSLATED': ...

Well, yeah, the result of that would be helpful...
