Yes, there have been several memory-scribblish reports.  Until this one's
found I'm not sure there's much we can do with them.

I'll do an overnight run with CONFIG_DEBUG_SLAB, see if that catches
anything.  Although AFAICT it just fixes the bug.

Beyond that, I'm rather stuck.  I'd probably have to drop a pile of sched
patches, see if that improves things for people.  But if we cannot spot a
bug in those patches then it's probably in mainline and it will bite
people in generally random and rare ways.
