I just wonder whether you *really* need that loop at all?

If something went wrong with the attempted task move - you raced with
another cpu, or whatever - is there any real reason to even bother to
try again?

It's just a heuristic, after all, and we'll come back to balancing later.

The minimal patch looks good, but I did want to ask whether people
have considered just removing the looping entirely?
