> Current the JvmPauseMonitor.SLEEP_TIME is hard coded to 500ms and the default
> value of sleepDeviationThreshold is 300ms. In this case, JvmPauseMonitor may
> not be able to detect an extra sleep violating the threshold. Consider the
> following:
> # JvmPauseMonitor sleeps at T
> # A pause start at T+50ms and ends as T+400ms, i.e. the pause is 350ms
> # JvmPauseMonitor wakes up at T+500MS and detects no extra sleep.
