From: Sukadev Bhattiprolu <suka...@linux.vnet.ibm.com> Subject: [PATCH 2/2] Must unfreeze while stopping container
As pointed out by Dan Smith, when a container is being stopped, it must also be unfrozen after posting the SIGKILL. Otherwise if the container is frozen when the SIGKILL is posted, the SIGKILL will remain pending and the lxc-stop command will block until lxc-unfreeze is explicitly called). (lxc-stop waits for the container to exit and close the socket but since the container is frozen, lxc-stop will block).
