                 * 2. returnValue = tryLock() for an entry
                 * 3. if returnValue == false
                 * 3-1. flush all entries (which already acquired locks) to the next operator
                 * : this will make all those entries reach commit operator so that corresponding commit logs will be created.
                 * 3-2. create a WAIT log and wait until logFlusher thread will flush the WAIT log and gives notification
                 * : this notification guarantees that all locks acquired by this transactor (or all locks acquired for the entries)
                 * were released.
                 * 3-3. acquire lock using lock() instead of tryLock() for the failed entry
                 * : we know for sure this lock call will not cause deadlock since the transactor doesn't hold any other locks.
                 * 4. create an update log and insert the entry
                 * From the above logic, step 2 and 3 are implemented in this before() method.
