It has been a while, but I think this will show a leak:

while 1:
    d = {'a': 1}

Via regular Python, it works without a leak, but with mod_python, it leaks 
(buggy version).
Reference counting is supposed to take care of this (and I don't see any 
cycles).

Status in libapache2-mod-python in Ubuntu Feisty: In Progress

Bug description:
Binary package hint: libapache2-mod-python

Hello,
__repr__ leaks only under mod_python. The problem seems to be related to a 
mod_python bug: 
http://mail-archives.apache.org/mod_mbox/httpd-python-dev/200610.mbox/[EMAIL 
PROTECTED]

Can you please backport this bug fix to Edgy/Feisty. The mod_python devs
fixed it in 3.3.x and that will only get into Gutsy.

It is a one liner fix:
