At the moment the only way you can guarantee that a publish has gone 
through is to publish inside a transaction - when the transaction commit 
completes the message is on disk (assuming durable queue / persistent 
message). This is a little heavyweight though. In the future we intend 
to introduce streaming publisher acks to do the same job in a more async 
way.

Cheers, Simon
