CGI conundrum

[Robin Becker]

My ISP allows python cgi scripts to run as user nobody. I want some
scripts to save files in a world readable directory which has to be
owned by nobody so scripts can create files. I would like to clean the
files up regularly, but can't use standard cron as I can't run as
nobody. Do I set up a cgi script to do the job for me and get my cron
job to request it using urllib or is there some more obvious way?
