	hello, peter,

	yes.  :)  right now, there's no easy way to run a test and get 
stats for just that test, since the counters persist -- so you have to do 
things like run a test, unmount, remount, etc.  this is a quick way to get 
stats collected over an arbitrary period.  and it's not very complicated, 
really.

	i don't think a shell/perl/python/etc script would be anywhere as 
useful a substitute.  and with neil's suggestion about adding an optional 
timeout to make it easier to use -in- scripts, i think we're on the right 
track with this approach.

	.. thoughts/ideas?

	thanks,

	d
	.
