OK. I look forward to seeing your patch. One of the most important
things that we did was to get all of the data for a single socket in a
structure, and create "choke point" functions for sending and receiving,
which is especially important for TCP and TLS (which both need to deal
with congestion, partial messages, and multiple messages).
I look forward to working with you towards a common code base,
Charles
