  Hum, I'm running elm here and I know what you're talking about.  I've
never looked at lock.c, but that should be correct, AFAIK.  No normal user
should be allowed to call setuid or setgid, so a -1 is the proper return
value.  Correct me if I'm wrong, please.

  I've set /var/mail to drwxrwxrwt root.wheel, and /usr/local/bin/elm to
-rwxr-sr-x bin.bin.  With the sticky bit set on /var/mail, nobody can muck
with others files, and they're permed rw for owner only.  I'd been meaning
to go back and look to see if elm really even needs the setgid to run (I
think so).
