[Python-Dev] PEP 418: Add monotonic clock

I'm not sure I understand your suggestion correctly, but replacing
time.time() by time.monotonic() with fallback won't work, because
time.monotonic() isn't wall-clock time: it can very well use an
arbitrary reference point (most likely system start-up time).

As for the hires() function, since there's no guarantee whatsoever
that it does provide a better resolution than time.time(), this would
be really misleading IMHO.
