// osRelaxMinNS is the number of nanoseconds of idleness to tolerate
// without performing an osRelax. Since osRelax may reduce the
// precision of timers, this should be enough larger than the relaxed
// timer precision to keep the timer error acceptable.
const osRelaxMinNS = 0
// osRelax is called by the scheduler when transitioning to and from
// all Ps being idle.
