AFAICS, what Thomas proposes would be exactly equivalent to root running
scripts owned by non-root users --- in this case, if session user is
root then functions written by other people would be allowed to do
things they normally shouldn't be able to do. It strikes me as a great
loophole for Trojan-horse functions. Not that a sane superuser would
run functions controlled by other people in the first place.
