>Description:
	InnoDB: Error: row_search_for_mysql() is called without ha_innobase::external_lock()
>How-To-Repeat:
	create table foo ( data int );

	create temporary table tmp_foo (select  * from foo limit 0);
	insert into tmp_foo (data) values (1);

	lock tables foo write;
	# add ", tmp_foo read" to the above, to avoid the error.
	#"LOCK TABLES is permitted (but ignored) for a TEMPORARY table."
	#    -- http://dev.mysql.com/doc/refman/5.0/en/lock-tables.html

	delete from foo;
	# The next statement causes
	# InnoDB: Error: row_search_for_mysql() is called without ha_innobase::external_lock()
	insert into foo (select * from tmp_foo);
	unlock tables;

	drop table tmp_foo;
	drop table foo;

>Fix:
	Lock the temporary table, though mysql docs say you shouldn't have to.
