basic.publish is asynchronous; there is no confirmation.

How is your lib dealing with errors during publish? On way to deal with 
channel.flow{active=false} in a client is to mark the channel as blocked 
and return/raise an error on all subsequent publishes.

You may also want to expose the channel.flow events to apps, so they can 
do internal flow control.
