For what it's worth, you might do better to try "kill -HUP" a process 
first, then "kill -TERM", before resorting to "kill -9" (aka "kill 
-KILL").  Using less than maximum force gives the process a chance to 
notice it is supposed to go away and shut down more cleanly.  This may 
help.

However, if you do get a process stuck which won't go away when you 
kill -9 it, consider doing a "ps axl" and see what it's WCHAN is stuck 
on.  (BTW, be sure you can discriminate between a zombie waiting for a 
parent to reap it's exit status, ie, "STAT" is "Z"...)
