If the API allows us to query the tsc frequency, it would simply

The API only allows querying the processor frequency. In the
constant_tsc case, the highest processor frequency is likely going to be
the actual TSC frequency, but I don't think it's a guarantee;
theoretically, it could be faster on normal hardware ... or slower on
overclocked hardware with an externally clocked TSC.
