    Pavel is right: the other they I made the mistake of running (as a normal
    user) "cp /dev/zero file.txt" in our production system instead of "cp
    /dev/null file.txt" and the CPU utilization went way up and nothing could
    get done. The server was useless until I figured out what was going on
    and killed the cp. This really is a DoS attack :-(

    I haven't tried Andreas' patch, though.
