I am wondering whether your testing method will work. Since if there is
only one thread in the system, yield will have no effect. But in your
description, there are only one thread. Our testing purpose is to verify
that yield method will idle CPU (if there are more than one threads running)
, while sleep will not idle CPU.

Maybe it is my mis-understanding of your description. It is highly
appreciated if you could write down your ideas into sample source codes.
