True, I haven't run tests on my computer that many times yet to say what
it really is. I based that 2% figure on what I see with p_iosx, which is
an Intel Mac. Most of the tests it runs seem to have less than 1%
difference between the runs. It is conceivable that the dual core nature
of the machine smooths down the differences a lot.
