Does the selftest for this ever actually schedule()?
At this point I'm not sure. This code has been in since the beginning. So its seen a lot of soak time.
I see it talking about context switching, but I don't immediately see how it would.
We were trying to force parent and child to run on the same CPU. I suspect something is wrong in the timing of that test.
