I'm trying to reproduce this problem, but with no luck.

With the following patch to quixote 2.0,
and running 'server/scgi_server.py', with
my Apache/1.3.31 (Debian GNU/Linux) using
mod_scgi to talk to the SCGI server on port 3000,
with a LocationMatch in the apache config for
SCGIServer 127.0.0.1 3000
SCGIHandler On
..  I can load, reload http://host/s/ as fast
as I want, and the Powered by Apache comes up
every time, whether from Explorer or Firefox on Win200Pro
or Firefox (mac) or  Safari.

Can you think of anything I'm missing that might
help trigger this?

The patch just modifies the demo to have a static directory,
and also also changes the SCGI handler a little in how
it sets SCRIPT_NAME and PATH_INFO.
