      mysqltest: At line 149: query 'RENAME TABLE t3 TO t3_bak' failed: 1213: Deadlock found when trying to get lock; try restarting transaction
       
      The result from queries just before the failure was:

      a	b
      SELECT * FROM t2 ORDER BY a;
      a	b

      RENAME TABLE t3_bak TO t3;
      include/start_slave.inc
      connection master;
      TRUNCATE t1;
      TRUNCATE t2;
      TRUNCATE t3;
