Yeah. I alluded to that later in my message, though not very clearly.

The main point is that you have to handle WANT_x.

I also forgot to mention that Eric Rescorla's book calls renegotiation 
"rehandshaking", so someone trying to understand this process (in SSL/TLS 
versions prior to 1.3) might also want to look for that term.
