Define the minimum fractional period in terms of hz. We know hz is
a magnitude smaller than itc_freq. A minimum period of 10*hz is
sufficient precision. As a side-effect, the number of clocks per
second, when the machine is idle, dropped by more than 50%.
Be anal and define the maximum period to be at least 4G seconds.
With a 64-bit counter and an ITC frequency that's expected to be
always less than 4Ghz, it takes longer than that to wrap around.
