Now that we are self-timed, the only reason white the active input block is null may be a zio buffer-full situation. We need to keep the loop running anyways (by discarding one sample), because we miss notification when the buffer has new space. We can't change zio to this aim, as it would be extra code in a hot path: we'd better loose one block when the buffer is full, we would loose it soon after anyways, since the system is overloaded.
