So I haven't tracked down all of the bug reports yet. But the
few bits I have seen make it likely. First the task_mmu change
was one of the largest change in logic I had to make. Second
the ugly bug reports seem to be about an extra decrement. Third
it seems to be my task_ref work that is the most implicated.
I will certainly follow and see what I can do to confirm that I have
gotten everything.
