> 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.
