    Keep in mind that Ken Thompson & Dennis Ritchie did not decide on a
    non-preemptive strategy for UNIX because they were unaware of such
    methods or because they were stupid. And when Rob Pike redesigned a new
    "unix" Plan9 note there is no-preemptive kernel, and the core Linux
    designers have rejected preemptive kernels too. Now it is certainly possible
    that things have change and/or all these folks are just plain wrong. But
    I wouldn't bet too much on it.
