On this theme: from the heights of my blissful ignorance (started
learning python and its library 2 weeks ago or so), I apparently
devised a way to use the facilities of the cgi module with mod_python
_without_ using the cgihandler.  I do something like this:

import cgi
from mod_python import apache

def handler(req):
    req.content_type = "text/html"

    env, si, so = apache.setup_cgi(req)
    formData = cgi.FieldStorage()
    for key in formData.keys():
        req.write( str(key) + " : " + str(data[key].value) + "<br>" )

This works without the need to specify cgihandler in the apache
config.  Not sure whether it's the Right way to handle things, or if
it avoids the leaking, but I thought it was worth sharing.. YMMV.
