One somewhat non-obvious point here -- as the primitive operation for
profiling, retrieving the current time with high resolution should be as
fast an operation as possible.  In addition, it should preferably take
near-constant time, so care should be taken to avoid any operations that
may vary in run time.

My assumption was that the fastest possible thing in PIR was a JITable
op -- is that not still the case?
