I know it's not quite what you're looking for, but if disk contention is 
causing the problem then using a script to pause/unpause commercial flagging 
that's only looking at CPU usage is like using the weather to predict profit 
margins.  Yes, they sort of affect each other, *but*...

I'd recommend using ionice instead.  ionice : disk :: nice : cpu.

(man ionice if that didn't make any sense.)
