Are you accessing the "session" object in the error page?

I have no access to mod_python source code right now to check,
but vaguely remember that if error page tries to access "session"
object it will deadlock. This is part of the reasons for having the
PSP object check if req.session exists and use it instead of creating
a new one each time, as proposed in one of the JIRA bug reports
I have posted. I'll post the JIRA link later.
