    Why don't you get with the C++ guy on the list talking about C++ kernels,
    Eray Ozkural ( and the two of you design a processor
    that's optimized to run C++ with 0 overhead memory protection (3 clocks max
    to go through a ring 3 -> 0 gate). Who knows? Maybe you could design
    a new processor for us to use that just implements two super RISC
    instructions, 'set bugs off' and 'do what I'm thinking'.
