thd->enter_cond() and exit_cond(), so that the I/O thread accepts to stop when it's waiting for relay log space. Reset ignore_log_space_limit to 0 when the SQL thread terminates. mysql-test/r/rpl_relayspace.result: result update mysql-test/t/rpl_relayspace-slave.opt: smaller relay_log_space_limit to speed up things. mysql-test/t/rpl_relayspace.test: Less queries in the test, to make it simpler. Testcase if the IO thread blocked in wait_for_relay_log_space accepts to stop when STOP SLAVE. sql/slave.cc: thd->enter_cond() and exit_cond(), so that the I/O thread accepts to stop when it's waiting on cond (waiting for relay log space). Reset ignore_log_space_limit to 0 when the SQL thread terminates.
