By jmikola:

ORM happens to have a `__clone()` implementation for its QueryBuilder (see: [here](https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/QueryBuilder.php#L1097)), but ODM does not. We'll have to implement that.

The alternative would be for this class to create new QueryBuilders on-demand, but that would change the constructor interface significantly.
