> Don't the Handshake packets consume cwnd also?

@martinthomson That's exactly the problem. They consume cwnd, although they're not even lost (as in "dropped by the network"), just dropped as undecryptable by the peer. In this situation, freeing up this cwnd is only possible after completion of the handshake, when all loss recovery state for non-1-RTT packets is dropped.
