One problem undoubtly arising is, steps should sometimes be done at {almost,exactly} the same time. We trust the timer to deal properly with very short or even zero periods. If a step can't be done in time, the timer shall do the step as soon as possible and compensate for the delay later. In turn we promise here to send a maximum of four such short-delays consecutively and to give sufficient time on average.
