[mod_python] Session Freezing using mod_python.Session

Hi, Graham.

I think Kenneth is referring to section 4.8.1:

"If session type option is not found, the function queries the MPM and
  based on that returns either a new instance of DbmSession or
MemorySession. MemorySession will be used if the MPM is   threaded and
not forked (such is the case on Windows), or if it threaded,   forked,
but only one process is allowed (the worker MPM can be configured   to
run this way). In all other cases DbmSession is used."
