One thing I found is that for some reason (which may very well make 
sense, because in a typical scenario it displays how far you're from 
interface driver dropouts), some audio programs seem to display the 
maximum load on a single core, not the averaged load over all cores, as 
Windows' task manager does.

There is a strategy that you may try to check (on multicore or 
multiprocessor systems) on which core your audio interface driver is 
running and then (also using task manager in the "Process" window) keep 
your audio app (e.g. Bidule) from using that core. Careful with 
hyperthreading architectures (e.g. Nehalem) - you need to remove them 
from the entire physical core (which is two cores in the task manager 
display). Then again, Windows XP generally has problems with 
hyperthreading architectures (or so I heard)...
