> Currently, timeouts in NAKACK are static, e.g. 300,600,1200.
> The goal is to make the retransmission timeouts a function of the actual average retransmission times. Ideally, we maintain rolling averages of actual retransmission times per sender and adjust the retransmit timeout based on these values.
> This would dynamically slow down retransmission on heavy traffic/congetion/message loss etc, and speed it up when those problems disappear again
