Use ResourceOwners in the snapshot manager, instead of attempting to track them
Alvaro Herrera <alvherre@alvh.no-ip.org>
Use ResourceOwners in the snapshot manager, instead of attempting to track them by hand. As an added bonus, the new code is smaller and more understandable, and the ugly loops are gone. This had been discussed all along but never implemented. It became clear that it really needed to be fixed after a bug report by Pavan Deolasee.
