Hi Laura,

what a terrible subject line! ;-)

I sometimes use os.system with pskill from - this should 
do what you want.

I do get my pid from some spawn-variant, IIRC. This should be more 
reliable than killing by name or parsing ps output (since you might 
kill the wrong process if there are multiple processes with the same 

What exactly doesn't work with your spawning? Could you post the spawn 
call you're using?
