There are no 'gotchas' except that if you run parallel code or benchmarks,
the timings may be hard to reproduce, depending on what processor a
particular thread/
benchmark ran on.

If this turns out to be a problem, you may want to specify benchmarks
and things to
run on a particular CPU using runon(1)
