TLS transports a stream of bytes. Saying a particular TLS packet must contain
just one stanza is like saying a particular TCP packet must contain just one
I don't think a TLS lib would ever cause real delay, but it might attempt to
put two sets of recently-written bytes into the same packet (just like a TCP
stack might do). This is perfectly acceptable, and should remain so.
