# TEST	test011
# TEST	Duplicate test
# TEST		Small key/data pairs.
# TEST		Test DB_KEYFIRST, DB_KEYLAST, DB_BEFORE and DB_AFTER.
# TEST		To test off-page duplicates, run with small pagesize.
# TEST
# TEST	Use the first 10,000 entries from the dictionary.
# TEST	Insert each with self as key and data; add duplicate records for each.
# TEST	Then do some key_first/key_last add_before, add_after operations.
# TEST	This does not work for recno
# TEST
# TEST	To test if dups work when they fall off the main page, run this with
# TEST	a very tiny page size.
