Creating a manager with the db_manager() method can cause unexpected
behavior. Consider the following:
{{{
class MyModel(models.Model):
objects = models.Manager()
ro_objects = objects.db_manager('ro')
}}}
There are certain situations where ro_objects becomes the 'default'
manager of the object. Both of these managers have the same
'creation_counter'.
