We were seeing flakes in test 320, seemingly because the 'docker run' command would sometimes send a delete request for the container it had started, before dying. We need the container to carry on running so we can check it does get attached when the cluster reaches quorum. Sending signal 9 means the command dies immediately and does not get a chance to delete the container.
