    This case means `docker stop` is in progress (`killed == true`): https://github.com/apache/mesos/blob/e36e3b9989b1097dca9597097dd51d24aaba48fa/src/docker/executor.cpp#L473-L525.
The container might still be running. If `docker stop` fails or hangs for more than 3 seconds,
the executor will terminate, but the docker container might be running.
