Subject: latencytop kills volanomark throughput.  yawn?

Greetings list,

The moral of this story is probably "don't do that", but...

While doing some scheduler testing recently, I ran volanomark, and
accidentally left latencytop running.  The results were decidedly
un-good, and the reason appears to be that MUCH time is spent crawling
over a list of (106 loaded) modules.
