Currently there's an implicit requirement that users of SimulatedNetwork should call it repeatedly, even if the return value of NextDeliveryTimeUs is unset. With this change, it will indicate that there might be a delivery in 5 ms at any time there are packets in queue. Which results in unchanged behavior compared to current usage but allows new users to expect robust behavior.
