Ahhhh.....no....

When you do a "kill" you are sending a "signal" to a process and that process will
act upon it depending on the signal.  For example, if you did a "kill -1" to the
named process it will cause it to reread its configuration files and zone files.

Whatever process you send the kill to must be in a state where it can receive and
process the signal.

If you process is stuck in a WAIT state it won't "catch" the signal.  The same is
true of Zombie processes.  Zombies are child processes whose parent process has died
unexpectedly.;
