	guys, 

	I've evidently had too many pain meds; this shelll script should 
	be easy.  say that I have a utility xxx running sometimes.  xxx is
	soaking up a chunk of my load.  I have to use top to find if
	xxx is running, then kill -9 to kill xxx and have a steady load of,
	say, between 0.10 and 0.15.  what's the script that can do this?

	gary
