Ensure that :func:`time.sleep(0) <time.sleep>` does not degrade over time
on non-Windows platforms. Patch by Bénédikt Tran.
Ensure that the duration of :func:`time.sleep(0) <time.sleep>` is as small
as possible on non-Windows platforms when :manpage:`clock_nanosleep(2)`
or :manpage:`nanosleep(2)` are used to implement :func:`!time.sleep`.
