Re: [TLS] CCS and key reset and renegotiation

I guess, pedantically, the appdata is a loop.  But renegotiation is going away, and I need to think about resumption a bit.

Perhaps Peter, when he sees these notes in his timezone, can comment.

There is a loop! When receiving application data the state doesn't advance.

Also renegotiation loops, as does resumption.

As for the ladder diagram, early in the RFC there is one.
