Comment 10 for bug 1245775

It seems the controller has changed only slightly since Amala's proposal (https://github.com/openstack/glance/blob/9622189e728468e0cd8b358d1ebcb417f16d449f/glance/api/v1/images.py#L1076). It's unclear to me if this is still potentially an issue without trying to reproduce this and seeing if it persists.
