 Yeah, my fault :-P.  As best as I can tell (from revisiting the code),
 content-gap is a superset of ack-above-hole.  Content gaps can also occur
 in situations where we're not expecting to see ACKs (for example, due to
 split routing, or because we're not processing traffic from the receiver).
 I think merging the two into a single content_gap event would make sense.
