    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
