Yesterday someone suggested using "kill 9 $pid" as a better way of getting
rid of zombies instead of "kill -9 pid". I don't see how that could have
the desired effect.
The way that "kill 9 $pid" behaves is that it interprets 9 and $pids as
processes to send the desired signal to. Since no signal is specified,
the default signal of SIGTERM is used: kill -TERM 9 $pid.
On my box, process 9 (ps -f -p 9) is kacpid. So when I run "kill 9 $pid",
i get a nice friendly message stating that i don't have proper credentals
to send it a signal.
