Most local change that occurs during a pull are doing within a `transaction`. Currently this mean (1) adding new changeset (2) adding obsolescence markers. We want the two operations to be done in the same transaction. However we do not want to create a transaction if nothing is added to the repo. Creating an empty transaction would drop the previous transaction data and confuse tool and people who are still using rollback. So the current pull code has some logic to create and handle this transaction on demand. We are moving this logic in to the `pulloperation` object itself to simplify this lazy creation logic through all different par of the push. Note that, in the future, other part of pull (phases, bookmark) will probably want to be part of the transaction too.
