27    double speed_endtime (void)
28        Call speed_starttime to start measuring, and then call speed_endtime
31        speed_endtime returns the time taken, in seconds.  Or if the timebase
32        is in CPU cycles and the CPU frequency is unknown then speed_endtime
36        If some sort of temporary glitch occurs then speed_endtime returns
46        or 1.0.  It's 0.0 when speed_endtime is returning seconds, or it's
47        1.0 when speed_endtime is returning cycles.
49        It may be noted that "speed_endtime() / speed_cycletime" gives a
50        measured time in cycles, irrespective of whether speed_endtime is
57        This is in seconds or cycles, as per speed_endtime.
71        works for both cycles or seconds from speed_endtime).
79        Call this to demand that speed_endtime will return seconds, and not
85        "speed_endtime() / speed_cycletime" will give times in cycles.
96    Allowing speed_endtime() to return either seconds or cycles is only a
