   Making a program setuid only changes the "effective" uid, leaving the
   "real" uid the same.  This used to be sufficient to prevent kill from
   killing it, but apparently not anymore.  I wonder if that's a bug or more
   SVID compliance? ...  --wnl

It's both:  a major mistake, introduced for the sake of SVID compliance.
