Per Gilles's suggestion, Mark at Stellartech ran latency and klatency  
with the TSC enabled "the hack" and without the TSC enabled. He also  
posted the CPU task measurements with our app running without the  
hack, which is horrible compared to when the TSC is on.

It looks like we are better off with the TSC. The worst case is much  
better, anyway.
