> If you have two connections with a consumer each on the same queue, and one of the consumers has consumed a message transactionally but not committed it.
> Then when failover occurs, if the second connection fails over first then it might "grab" the message before session::recoverDeliveries kicks in for the other connection.
> This means the message can get delivered more than once.
