Hi Chris,

Thanks for the pointer on the new notification on state change stuff, I'd 
missed that change.

Is there a blueprint or some such which describes the change ?   

 In particular I'm trying to understand how the bandwidth_usage values fit in 
here.  It seems that during a VM creation there would normally be a number of 
fairly rapid state changes, so re-calculating the bandwidth_usage figures might 
be quiet expensive jut to log a change in task_state from say "Networking" to 
"Block Device Mapping".     I was kind of expecting that to be more part of the 
"compute.exists" messages than the update.

Do we have something that catalogues the various notification messages and 
their payloads ?

Thanks,
Phil

This has been in trunk for a month or maybe a little longer.
