I'm not sure that the cascading delete (option #2) case would leave 
things in a messy state since we'd delete the stuff that we're actually 
orphaning today. If we don't cascade delete for you and just let the 
request fail if there are still allocations (option #1), then like I 
said in a reply to zigo, there are APIs available to figure out what's 
still being used on the host and then clean those up - but that's the 
manual part I'm talking about since nova wouldn't be doing it for you.
