WIN revert to Sleep(1) for yield
There are multiple ways on Windows to yield a thread:
* SwitchToThread: yields to any thread on same processor
* Sleep(0): yields to any thread of same or higher priority
on any processor
* Sleep(1): yields to any thread on any processor
So we stay with Sleep(1), as it also seems the only call, which
actually does some sleep and is not a busy wait.
