This test shouldn't need to guesstimate the frequency, just use a

will be as accurate as we can get. For hardware without a constant TSC,
well, buy
new hardware :-)
Thanks. That simplifies things. I encountered that number before but was
unsure if I could trust it for reasons I no longer remember.
