Why must get_timer() be used to perform "meaningful time measurement?"

If all of this is about time measurement, why not start with your dream
time measurement API, and go from there? And make it an optional
feature.

If the existing API, that has been used successfully for years,
primarily as a mechanism for detecting a time-out, has issues,
then let's resolve _those_ issues and avoid the "car-boat" ... the
vehicle that floats like a car and handles like a boat. ;-)
