Actually, 'killall' only seems to kill the current login shell and its subprocesses. However, when you run it during system shutdown or reboot, it really kills everything.

I posted bug report to the upstream, but perhaps as long as they are correct, it is worth while to roll back?

For reference, upstream bug report: http://sourceforge.net/tracker/?func=detail&aid=3536526&group_id=15273&atid=115273

If you give it a wrong option, it also kills everythings. I accidentally killed my X session when I ran "killall --help" when investigating this bug.
