max_statement_time not see in the global STATUS：Max_statement_time_exceeded

[william]

     when use the max_statement_time feature，the status ：Max_statement_time_exceeded can only be seen by own session，other session can not see，Here is typical example for that:

mysql> show variables like '%max_statement_t%';
+--------------------+-------+
| Variable_name | Value |
+--------------------+-------+
| max_statement_time | 1 |
+--------------------+-------+

mysql> show status like '%max_st%';
+-------------------------------+-------+
| Variable_name | Value |
+-------------------------------+-------+
| Max_statement_time_exceeded | 1 |
| Max_statement_time_set | 12 |
| Max_statement_time_set_failed | 0 |
+-------------------------------+-------+
3 rows in set (0.00 sec)

mysql> select * from information_schema.tables where table_rows > 0 group by table_schema;
ERROR 1886 (70101): Query execution was interrupted, max_statement_time exceeded

mysql> show status like '%max_st%';
+-------------------------------+-------+
| Variable_name | Value |
+-------------------------------+-------+
| Max_statement_time_exceeded | 2 |
| Max_statement_time_set | 14 |
| Max_statement_time_set_failed | 0 |
+-------------------------------+-------+
3 rows in set (0.00 sec)

but,when i connect from another session，i can not see the status variables to be change：
mysql> show status like '%max_st%';
+-------------------------------+-------+
| Variable_name | Value |
+-------------------------------+-------+
| Max_statement_time_exceeded | 0 |
| Max_statement_time_set | 0 |
| Max_statement_time_set_failed | 0 |
+-------------------------------+-------+

mysql> show global status like '%max_st%';
+-------------------------------+-------+
| Variable_name | Value |
+-------------------------------+-------+
| Max_statement_time_exceeded | 0 |
| Max_statement_time_set | 0 |
| Max_statement_time_set_failed | 0 |
+-------------------------------+-------+
3 rows in set (0.00 sec)

so，this is very bad for the understanding of server state
