If you have looked at this (above) and that isnt it, there is a sure fire
method to find it: WindView. this will analyze (in realtime) your processes
on each CPU, and you can instrument your code to find the problem areas.
It is very easy to use, and non-intrusive. Even without the instrumentation,
WindView exposes all tasks running. You can get this software for eval,
and try it out. You must be running rtmond for it to work.
