node.js - How to destroy firebase ref in node

Question

If I do this in node:

console.log('1');
console.log('2');

outputs:

1
2

And the process ends.

If I change it to this:

console.log('1');
var Firebase = require('firebase');
var ref = new Firebase('https://<some-base>.firebaseio.com/');
console.log('2');

outputs:

1
2

and the process continues.

I believe that this is because ref is keeping the process alive. I know that I can use process.exit but I would prefer to not do that. I actually don't want the process to exit anyway, I just want to make sure that I don't have a memory leak issue where my firebase ref lasts forever. Is there any way to destroy a firebase reference once I'm done with it?
