> We are sending a {{docker stop}} to the docker container with a timeout of 10 seconds
when we shut down a container. If the container does not stop after 10 seconds then we force
kill it. However, the {{docker stop}} command is a blocking call. So in cases where lots of
containers don't go down with the initial SIGTERM, we have to wait 10+ seconds for the {{docker
stop}} to return. This ties up the ContainerLaunch handler and so these kill events back up.
It also appears to be backing up new container launches as well.
