If you read the source code it calls a method called get_all_keys. Please realize, this does NOT get all the keys in the bucket. Passed to it is the maxkeys=0 argument which means no keys are returned and a single list call is made. Yes, it is still a waste of money, but just make sure you understand that it's not actually listing your entire bucket.
