I reported thet sched_yield() wasn't working (at least as expected)

practically 0. Somebody said that this was because `top` was
broken, others said that it was because I didn't know how to

schedular changes were made for the current version.
This is what I would expect if run on an otherwise idle machine.
sched_yield just puts you at the back of the line for runnable
processes, it doesn't magically cause you to go to sleep somehow.
