Description
naked_short_sleep is to coarse grained on contemporary hardware/os:es. 1 ms as minimum when we can complete an entire safe-point in 0.5 ms is a very long time. Sleeping a very short time instead yielding have several uses-cases. I will first add it SpinYield to get much smother back-off delay curve.
