I see. I also read that Apache's mod_wsgi has a mode where it
processes to running the python requests. So if you include this
option then
that won't be a problem any more.

I'll keep on running my Nginx and FCGI combination then. The idea
of hooking up Nginx straight to a python file with an WSGI app inside
was very alluring to me, but I'll just have to wait. I don't really
to switch to Apache.
