BTW, I have experimented with the XML-RPC patch for Mailman 2.1.6:

 http://sourceforge.net/tracker/index.php?func=detail&aid=1244799&group_id=103&atid=300103

It seems to work nicely from "command-line" Python, although I haven't
yet got around to driving it from within Zope.

What you really buy with that import is that other people have thought
about, and fixed bugs for, the race conditions involved in creating
tempfiles.

In a "locked down" configuration, the user as whom Zope runs won't be
able to write into any directory on the system *except* the 'var'
directory (and a 'logs' directory if you feel obsessive about keeping
the logs elsewhere), so that works out well.
