OK. It looks like I need to add code like this to the location node:

```auto
this.on('close', function(removed, done) {
    if (removed) {
        // This node has been disabled/deleted
    } else {
        // This node is being restarted
    }
    done();
});

```

However, I'm not sure how to identify the correct callback function to remove from the array in the server node... I suppose instead of an array of functions, I would create a hash, but what identifier for a location node can I send when adding the callback function? Is `node.id` a thing?
