In recent discussions on improving the text for the tx 'class' in the 
0-9-1 spec there appeared to be some disagreement around the atomicity 
guarantee.

In particular, I understood from comments by members of the RabbitMQ 
team that though effects of all contained (publish and ack) operations 
are visible if the the commit is successful, RabbitMQ does not guarantee 
that none of them would be visible in the event of a failure.
