          Scenario of the BUG#40731 ("Maria: hang (probably in page cache) under concurrency"):
          T1: Disable logging for the table
          T1: Start inserting into the table
          T2: Tries to lock the table so waits.
          T2: Tries unlock and relock during the process see that the table has disabled logging and reenables it
          T1: Got DBUG_ASSERT because suddenly start use table with transaction switched on which is not expected during bulk insert
