+# Stress the storage engine with rapid CREATE/DROP TABLE/INDEX
+# and following SELECT/INSERT/SHOW etc.
+# Subtest 8 variants (8A - 8D)
+#
+# The variables
+#     $loop_size -- number of rounds till we look at the clock again
+#     $runtime   -- rough intended runtime per subtest variant
+#     $engine_type -- storage engine to be used in CREATE TABLE
+# must be set within the routine sourcing this script.
+#
+# Other stuff which must already exist:
+# - connection con2
+# - stmt_start and stmt_break prepared by the default connection
+#
+# Please look for more details within include/ddl1.inc.
