Great. Codegen is definitely the way to go since it will allow you
to keep up with the changes to the spec. Though you may want to grab the 
version of the xml spec from our dotnet client repo since it contains 
the rabbit-specific extensions. 
http://hg.rabbitmq.com/rabbitmq-dotnet-client/raw-file/default/docs/specs/amqp0-9-1.xml

Btw, the reason we don't use the xml in our server codegen, and instead 
have a json version of the spec, is because of legal issues with the 
AMQP XML spec that the Debian folks were unhappy about. This has since 
been fixed with the release of the stripped versions of the XML spec 
under a different license. But we haven't found the time to switch to 
using that.

Yes, that is possible.

You were just lucky. Shorten the frame size, use very large messages
and lots of channels and I am sure you'd see some interleaving.
