Um, actually, you probably want to turn -off- the compile option for making
CPU idle calls when bored.  The result should eat more energy, but if you're
plugged into wall power you shouldn't care.

In the ideal world -it- wouldn't care - it would notice through the apm code
that you're "AC online" and would never bother to issue idle calls.  I don't
think it's that bright yet.  Anyone who knows how to read that glop of code
who knows better than I, please advise...

I think this maybe also responsible for some systems getting a sliding clock 
time.  If you switch over into slower CPU but the sysclock thinks a tick is
a smaller portion of realtime... another thing where reading the code might
bear a clue?

Anyone have experience with the 15pre20 kit from woody, and whether it helps
or has no effect in this space?
