Syntax:
KILL thread_id

Each connection to mysqld runs in a separate thread. You can see which
threads are running with the SHOW PROCESSLIST statement and kill a
thread with the KILL thread_id statement.

If you have the PROCESS privilege, you can see all threads. If you have
the SUPER privilege, you can kill all threads and statements.
Otherwise, you can see and kill only your own threads and statements.

You can also use the mysqladmin processlist and mysqladmin kill
commands to examine and kill threads.

Note: You cannot use KILL with the Embedded MySQL Server library,
because the embedded server merely runs inside the threads of the host
application. It does not create any connection threads of its own.
