    AFAICT Alan Cox et al are saying that low-latency
    gives better latency than -preempt, but that if lock-break
    is added to -preempt, the results are basically the same.

    IOW lock-break + preempt =~ low-latency as far as the
    latency question is concerned.

    Admittedly my observations have been more from
    an "end-user" point of view, because at the end
    of the day, what I experience while using Linux as
    a multimedia/gaming platform is worth more than a
    barrel of benchmarks - and while kernel compilation
    time is of interest, it is just _one_ benchmark in the
    greater scheme of things. (not to mention that that
    benchmark result could probably be matched in a
    non -preempt kernel via /proc tuning)
