We should also allow the ack mode to be specified as an argument to the listener or sender (currently it's hardcoded to DUPS_OK). We should also allow disabling of the queue drain by a param. If you just want to measure the consume rate, i.e. send a bunch of messages then after that, consume them, currently it's not possible since it assumes the listener must be started first and all messages drained.
