This You cannot create orphan resources with UBC. All resources have an owner. You might be able to construct a hypothetical scenario where I commit all my resources to other people but I cannot create orphan resources or leak them. Even if I am the only user of a given UBC my counter will survive until the last object is freed, not until I log out. If I log back in my resource accounting is still there and nothing has escaped.
