Advisory backoff works much better - please see the attached graphs. The 
results without throttling or backoff look good, but for higher loads 
the success rate collapses spectacularly - I haven't been able to get 
any precise figures because the message queues get so long I run out of 
RAM. :-)

Cheers,
Michael
