Problem:- When we issue FTWRL with shutdown in parallel, there is race between FTWRL and shutdown. Shutdown might destroy the mutex (pool->LOCK_rpl_thread_pool) before FTWRL can lock it. So we can get crash on FTWRL thread Solution:- mysql_mutex_destroy(pool->LOCK_rpl_thread_pool) should wait for FTWRL thread to complete its work , and then destroy. So slave_prepare_for_shutdown will just deactivate the pool, and mutex is destroyed later in end_slave()
