@ianswett pacing or limiting burst is the right idea. TCP RFC limits the burst to IW but it says do that after an idle period of an RTO. Presumably the authors and community considered that period to be small enough that network capacity / conditions hadn't changed drastically. 

Implementation wise how would we do this without a timer? If not pacing, when would one decide to cut cwnd back to restart cwnd (say IW)?
