    so the case where you predict very short but is actually "indefinite", the real
    solution likely is that we set a timer some time in the future
    (say 100msec, or some other value that is long but not indefinite)
    where we wake up the system and make a new prediction,
    since clearly we were insanely wrong in the prediction and should try
    again.

    that or we turn the prediction from a single value into a range of
    (expected, upper bound)

    where upper bound is likely the next timer or other going-to-happen events.
