mysql使用myisam的时候锁表比较多，尤其有慢查询的时候，造成死锁.这时需要手动kill掉locked的process.使他释放.
(以前我都是重起服务)..惭愧啊..
演示:(id 7是我用python 来连过来的一个会话,虽然是状态是sleep,为了演示，干掉他)
mysql> show processlist;
+----+------+-----------+------+---------+------+-------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+----+------+-----------+------+---------+------+-------+------------------+
| 7 | root | localhost | yy | Sleep | 154 | | NULL |
| 8 | root | localhost | NULL | Query | 0 | NULL | show processlist |
+----+------+-----------+------+---------+------+-------+------------------+
2 rows in set (0.00 sec)
mysql> kill 7
-> ;
mysql> show processlist;
+----+------+-----------+------+---------+------+-------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
