[issue21302] time.sleep (floatsleep()) should use clock_nanosleep() on Linux

[Benjamin Szőke]

Benjamin Szőke <egyszeregy at freemail.hu> added the comment:

Absolute timeout implementation via SetWaitableTimer() and GetSystemTimePreciseAsFileTime() is always better because it can reduce the "waste time" or "overhead time" what is always exist in any simple interval sleep implementation. Moreover, it is the only one which is eqvivalent with clock_nanosleep() implementation of Linux which is now the most state of the art implementation for precise sleeping.

So, my opinion is that absolute timeout implementation could be the most modern and sustainable for future python.
