      BUG#35583 mysqlbinlog replay fails with ERROR 1146 when temp tables are used
            
      When using CREATE TEMPORARY TABLE LIKE to create a temporary table, 
      or using TRUNCATE to delete all rows of a temporary table, they 
      did not set the tmp_table_used flag, and cause the omission of
      "SET @@session.pseudo_thread_id" when dumping binlog with mysqlbinlog,
      and cause error when replay the statements.
            
      This patch fixed the problem by setting tmp_table_used in these two
      cases. (Done by He Zhenxing 2009-01-12)

+# ==== Purpose ====
+#
+# Test if statements used temporary tables are binlogged correctly
+#
+# ==== Method ====
+#
+# Use two connections, use temporary tables on both of them, and by
+# switching connections between statements, the test can check if the
+# statements are logged with the correct thread id.
+# 
+# The statements current tested include:
+#   CREATE TEMPORARY TABLE
+#   CREATE TEMPORARY TABLE LIKE
+#   INSERT
+#   REPLACE
+#   UPDATE
+#   INSERT SELECT
+#   TRUNCATE
+#
+# Note: When adding new query statements, please add them between the
+# two 'flush logs'. And aslo please make sure the connection is
+# switched between each statement.
