    Hm, i'm not convinced about this one. Stupid question: what's wrong
    with ulimit -s?

    Also, if for some reason you dont want to (or cannot) enforce a
    system-wide stack size ulimit, or it has some limitation that makes
    it impractical for you - if we add what i suggested to the
    /proc/*/maps files, your user-space watchdog daemon could scan those
    periodically and report any excesses and zap the culprit ... right?
