Nice Ad Hominim. I mistype "call-gate" for "trap-gate", and now
I'm a religious zealot. See my other posting.

LMBench is a set of microbenchmarks that aren't very predictive of
real-world load characteristics. The best predictor of real-world
load characteristics is previous measurements in the real-world
under identical load (ie: if it too 500 cycles yesterday, it will
take 500 cycles today).
