Yes the figures are insane, but if the idle time is around 36 minutes, the
conversion to int will make a positive value look negative and we will exit the
conditional block. And if we don't think that we will ever get such insane idle
times or we don't want to care about them, then what about doing this instead:
} else if ((unlikely((int)idle_time > 2 * sampling_rate &&
