What is the purpose of the change
When you run
world-cli cardinal dev
then ctrl+C to quit you'll see a wierd error message about how the process already quit then the cli will display the help message.this occurs because when scott was messing with the cli he used a version of cardinal that hung during shutdown. So he used a force quit to kill it.
Now that cardinal handles shutdown properly and doesn't hang forever during start game the mechanism is now changed to wait 10 seconds and see if the cardinal shutsdown by itself. If it doesn't then force quit.
