PdoSessionHandler::LOCK_TRANSACTIONAL

Issues a real row lock. Since it uses a transaction between opening and closing a session, you have to be careful when you use same database connection that you also use for your application logic. This mode is the default because it's the only reliable solution across DBMSs.
