I still believe that measuring process time is better than
wall time and have tried hard to find suitable timers for
However, the tests using the various different timers have
shown that this approach doesn't work out due to the problems
with how process time is measured on the platforms in question
(Linux and Windows).
We should revisit this choice once suitable timers are
available on those platforms.
Note that even with the wall-time timers and using the minimum
function as estimator you still get results which exhibit
At least now we know that there's apparently no way to get it

Isn't that the whole point of such a discussion ?
I'll check in pybench 2.0 once I've tested it enough.
