I've been thinking of expanding the data manager API to add an optional tpc_rollback method. If tpc_finish returns a value and a data manager provided tpc_rollback and some other data manager fails in tpc_finish, then tpc_rollback would be used to *try* to recover from the other data managers failure. Note that even if tpc_rollback is implemented, it might fail if the transaction can't be rolled back (due, typically, to subsequent conflicting transactions).
