Does <http://www.oucs.ox.ac.uk/web/faq/index.xml?ID=safeperl> ring any
bells? :) I don't think the code which uses Safe.pm to implement that
environment (a perl program called cgiperl, plus a SUID root wrapper
for privilege management) is really released anywhere, but it is just
about limping along, although I seem to recall that we haven't managed
to get it to work with anything more recent than 5.10 yet.
