    More specifically, the "cooperating processes monopolize the cpu"
    scenario is at its worst when a shell script is used to drive the bochs
    simulator by single-stepping in order to generate instruction-level
    boot-time traces of the execution of custom executives.

    ./ | bochs is the method, where the contents of are
    trivially derivable from bochs' debugging interface (a couple of
    newlines and then repeating 's' indefinitely, then killing the process
    by hand when the exception is observed while tail -f'ing the trace).
