Interesting. That would explain the clock-like delays. Possibly it's nearly zero RTT in initial exchanges and then when venti has to do some work, things time out. You'd think it would only lead to needless retransmissions not increased latency but perhaps some calculation doesn't work properly with tiny values, causing one side to back off incorrectly.
