The "ruid" idea and prevent exec/fork of suid programs, is a nice idea but
is really security through obscurity.
If a hacker knows this patch is in place, he just replaces the shellcode
so instead of doing:
syscall exec /bin/sh
syscall chmod 666 /etc/passwd
or any other exciting piece of code you care to run. You need not launch a
separate process to run it.
