> 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.
