[Python-Dev] Drop the new time.wallclock() function?

[Kristján Valur Jónsson]

Interesting thought.
Althougn I don't see how that could fail on windows, if the QPC function is really just talking to a clock chip, surely that hasn't been virtualized.
Is there an actual example of windows hardware where this api fails (virtual or not?)  Perhaps there is no real need to have a fallback mechanism, and it would even be best to write such a mechanism inside the function itself, and just return getsystemtimeasfiletime() instead.

Btw., have you considered virtual machines?
I happen to run windows in Parallels or Virtualbox quite often.
There the "wall clock" stuff notoriously does not work.

It would be good (but difficult?) if the supposed-to-be-accurate clock could test itself, if it works at all, and replace itself with a fallback.

In my case, this causes quite a few PyPy tests to fail ;-)
