Just a gut feeling, but I suspect the exact throttling algorithm would 
vary too much from machine to machine and OS version to OS version to 
ever find a good threshold to avoid it.  The best thing to do would be 
to have the harness turn off CPU throttling when it starts.  (This is 
possible from the commandline under Linux, and I assume in Mac, but 
Windows might be a problem.)
