   Probably not going to happen. I read somewhere that if users are
   allowed to reap /tmp anytime at will, a malicious user can exploit
   some race condition in tmp file creation to do privilege
   escalation.

Could you dig up the article?  I can't see any reasons why it wouldn't
be utterly trivial to make such a program totally abuse safe.
