Principle:: an Architecturally visible unit of data can only become
visible after the causing instruction retires. A high precision
timer makes cache line [dis]placement visible; so either take away
the HPT or don't alter cache visible state too early.

And parallelism (e.g. multicores) can be used to emulate HPT, so "take
away the HPT" is not really an option.

That's exactly how they measured time in PoC.
