The way this is implemented here is not particularly nice, but will improve in the future once we implement spurious RTO decection #687 (where we'll need a packetHistory similar to Chrome's). In particular, we don't consider non-retransmittable packets for RTT measurements or for early retransmit. While that might impact performance in some edge cases, it shouldn't be worse than before :) Fixes #505.
