Even with 3 runs, I do not see any noticeable change in performance. I
am running the tests on emacs repo. I am running all tests on M$-XP
box (lenovo T61 series with Intel Centrino Pro, 1Gb RAM).
How do I get rid of cache if I have to restart the tests? I plan to
analyze the '--lsprof' output to see if there is different code path
and the so called hot/cold cache making any difference.
