Running Test App

go run consumer.go

The app will connect in batches of 2048 and then will wait forever. While it is waiting, kill it using CTRL-C. You will slowly see queues being deleted in the management UI. If you re-start the app, you should notice that the first batch takes much, much longer than before.
