Oh darn, mislooked what message it was.


Also, with regard to ending 0RTT, even without encrypted content
types. Either I am misunderstanding something, or:

- Client: Send ClientHello.
- Server: Read ClientHello.
- Client: Send 0-RTT & client cert.
- Server: Read 0-RTT & client cert.
- Client: Wait for server reply.
- Server: Wait for handshake message to end 0-RTT.
*deadlock*.
