Someone else might want that and/or a complete trace. I can see enough
to say it looks an awful lot like a little gremlin that's been plagueing

I don't think it matters much. I strongly suspect we'd just see more
of the same. Try commenting out the current->policy |= SCHED_YIELD in
__alloc_pages() just for grins (more or less).
