Comment 2 for bug 969229

It is possible and useful to remove the channel from the client dict immediately when the channel is closed, using appropriate event. The applied patch does it such a way, that the code like the following works correctly:

    try:
        yield self.chan.queue_delete(queue="chatrooms") # here the 404 happens
    except Exception,ex:
        print "Error deleting queue %s, ignored" % ex
        self.chan = yield self.conn.channel(1) # here the channel is recreated just because it is already removed from the dict
        yield self.chan.channel_open()
