> If a container is in the process of localizing when it is stopped/killed then resources are left in the DOWNLOADING state.  If no other container comes along and requests these resources they linger around with no reference counts but aren't cleaned up during normal cache cleanup scans since it will never delete resources in the DOWNLOADING state even if their reference count is zero.
