I've been running these for a couple days with no problems, although I
haven't been trying to reproduce the problem.  (Well, no problems
related to memory management.)

I suspect that my pet unnecessary-OOM-kill bug is still around, but
that's probably not related, especially since I can trigger it if I
stick 8 GB of RAM in this laptop.

Thanks,
Andy
