AsyncStunTCPSocket wasn't firing SignalSentPacket, which the bandwidth estimator requires for every packet in order to look up send times when feedback arrives. If the signal isn't fired, it always assumes feedback is arriving extremely late, and decreases the bandwidth by a factor of 2 until it reaches the minimum of 10kbps.
