[rabbitmq-discuss] Publishing: Connection timeout issue

[Alan Antonuk]

Couple notes:

- Doing a connection_close() implicitly closes all channels. You don't need
to explicitly close channels.
- If you get a connection timeout error while using the connection object,
the whole connection is dead. You won't be able to do a channel_close or
connection_close. The only thing you can do is destroy the connection
object (which should clean up any memory and close any partially open
sockets).

I'm not sure how you set up your exchanges/queues on the broker, but I
don't think it should matter what connection you publish your message over.
