    My personal feeling regarding this code was that it would be much simpler/cleaner
    to implement a driver for the "jump tracer"s implemented in various CPUs.
    Basically the CPU will write all jumps into a buffer by itself. That
    allows you to do many traces (although not latency traces) too.
