George: that seems to be to be a slightly different issue that what's reported here, unless I've missed the subtlety of what's reported here. I was under the impression that the _resize disks were being left around indefinitely, vs your concern that they're not cleaned up immediately.
There has been talk for quite a while about getting to a point where tasks are cancel-able within Nova, but at this point there's very little to work with to make that happen. The solution you've proposed would involve a db migration and multiple RPC changes while being primarily libvirt specific. Making that work generally across hypervisors will take a bit more abstraction and effort, and doing that in a backwards compatible way may end up being a challenge as well.
