[Python-Dev] Use QueryPerformanceCounter() for time.monotonic() and/or time.highres()?

Possibly we really do need two timers, one for measuring short
intervals and one for measuring long intervals? Perhaps we can use
this to decide on the names?
Anyway, the more I think about it, the more I believe these functions
should have very loose guarantees, and instead just cater to common
use cases -- availability of a timer with minimal fuss is usually more
important than the guarantees. So forget the idea about one version
that falls back to time.time() and another that doesn't -- just always
fall back to time.time(), which is (almost) always better than
Then we can design a separate inquiry API (doesn't have to be complex
as long as it's extensible -- a dict or object with a few predefined
keys or attributes sounds good enough) for apps that want to know more
about how the timer they're using is actually implemented.
