rli->save_temporary_tables and slave_open_temp_tables (in old 4.0 you could make "SHOW STATUS LIKE 'slave_open_temp_tables'" grow indefinitely by doing RESET SLAVE and replicating always the same CREATE TEMPORARY TABLE). It's critical to reset save_temporary_tables to 0 (otherwise you may later read memory which has been freed) so this changeset should go into 4.1. mysql-test/r/rpl_reset_slave.result: result update mysql-test/t/rpl_reset_slave.test: test for RESET SLAVE and creating twice the same temp table in the slave. sql/slave.cc: when we delete the slave's temp tables (when slave server shuts down and when RESET SLAVE), we reset 2 variables: rli->save_temporary_tables & slave_open_temp_tables.
