:-).

Alex: is it possible your program is multi-threaded, and you have one of
those shiny new hyperthreading P4s? Remote, but that could give you this
behavior..

But even otherwise, small discrepancies between wall clock and computed
CPU clock are not uncommon, and given that your running time is pretty
close to one CPU "HZ" tick, you can get weird anomalies like this.

Try timing "a 1000000".
