This is the patch I've prepared for Cinder to prevent users from exploiting the data leak issue or even to unintentionally leave leftover devices by deleting the cinder attachment record.

I have to cleanup the os-brick code, write the unit tests, and see how the "recheck_wwid" multipath config option interacts with it.
I also have to try and see if the issue also happens in FC, in which case I would need to modify the os-brick patch and also write a new one to add support for the "force" parameter in the "disconnect_volume" method.
Since there are some calls to Nova I would appreciate reviews from the Nova team to confirm that I didn't miss anything.
