Comment 38 for bug 1371827

Some of the findings with optimized build

i) Reproducible with opt build + without tokudb plugin and I_S tokudb tables

mysql> show processlist;
+----+------+-----------+------+---------+------+----------------+-------------------------------------------------------------------------+-----------+---------------+
| Id | User | Host | db | Command | Time | State | Info | Rows_sent | Rows_examined |
+----+------+-----------+------+---------+------+----------------+-------------------------------------------------------------------------+-----------+---------------+
| 4 | root | localhost | test | Query | 458 | Opening tables | REPLACE INTO `table500_tokudb_default_int` ( `c7` ) VALUES
( 6792960 ) | 0 | 0 |
| 6 | root | localhost | test | Query | 0 | init | show processlist | 0 | 0 |
+----+------+-----------+------+---------+------+----------------+-------------------------------------------------------------------------+-----------+---------------+
2 rows in set (0.01 sec)

mysql> show tables like 'table500_tokudb_default_int';
Empty set (0.00 sec)

mysql> select database();
+------------+
| database() |
+------------+
| test |
+------------+
1 row in set (0.00 sec)

mysql>

In above testcase table "table500_tokudb_default_int" is not present in test database, but in show processlist "REPLACE INTO `table500_tokudb_default_int`..." is in hung state.

ii) When I removed "LOCK BINLOG FOR BACKUP" statement from SQL file, it became non-reproducible with optimized build ( Tested with and without tokudb plugin)
