> The Proton raw_connection_t currently requires cooperation from the 
> application layer to complete a close.  There is a baked in assumption that 
> the application will always eventually provide a read buffer.  A second 
> assumption is that the peer (not necessarily a Proton raw connection) will 
> detect a read close on its side, and do a graceful close of it's write side 
> "soon".
> These incorrect assumptions can leave the raw connection in a hung state 
> waiting for non-existent wind up activity by the application or peer, 
> respectively.
