* Callback pattern that is easier to grok: each message has an optional nested return channel, instead of 2 nested streams * Return channel is in the Message structure: less arguments and return values to pass around * Caller can request a pipe as return channel, or pass its own. This makes proxying and advanced plumbing operations much easier. Signed-off-by: Solomon Hykes <solomon@docker.com>
