    I don't know about other people, but I suspect you're running into lock
    contention. Try using a post 5.3 snapshot (something from RELENG_5)
    since alc@ has set debug.mpsafevm=1, which lets many calls to the VM
    run without GIANT, which I suspect is your problem and why the system
    usage is all over the place. -sc
