      Bug#41194 - The point in time in which a transaction
      is visible as committed by all other transactions 
      should not occur before the point of durability.
      Durability occurs when the commit record is written
      to the serial log.  This is the call to 
      database->commit(this) in Transaction::commit().
      It needs to happen before the status is changed.
