[issue2281] Enhanced cPython profiler with high-resolution timer

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Sorry, the calibration loop actually looks correct in case of preemption, since it simply divides the TSC delta by the elapsed physical time (and both continue increasing monotonously when another thread runs). It is still vulnerable to the thread migration problem, though.
