> Some AMQP 1.0 messaging use-cases would benefit from the {{AsyncAutoCommitTransactions}}
optimisation that is already in use on the older protocols.
> For instance, for a publisher sending persistent settled messages, currently each message
is written to disk and sync before the next message is the buffer is processed,.  With this
optimisation, the syncs would be allowed to coalesce.  
> Care needs to be taken when the work includes actions that aren't non-transactional transfers
to ensure that transactions remain ACID.
