        On slower file formats like .doc you can probably drop the -t and rely on the
        estimations, on faster file formats ironically not specifying a timeout will
        result in a hilarious dramatic falloff in performance from thousands per second
        to teens per second as tiny variations from the initial calculated
        timeout will trigger a shutdown of the fftester and a restart and the
        startup time is woeful (hence the AFL_PERSISTENT mode in the first place)
