> Depending on when ContainersLaunch starts a container, {{KILL_CONTAINER}}
> when container state is {{LOCALIZED}} ({{LAUNCH_CONTAINER}} event already
> sent) can end up generating a {{CONTAINER_LAUNCHED}} event - which isn't
> handled by ContainerState: {{KILLING}}. Also, the launched container won't be
> killed since {{CLEANUP_CONTAINER}} would have already been processed.
