# TEST	test127
# TEST	Test database bulk update.
# TEST
# TEST	This is essentially test126 with duplicates.
# TEST	To make it simple we use numerical keys all the time.
# TEST
# TEST	Put with -multiple, then with -multiple_key,
# TEST	and make sure the items in database are what we want.
# TEST  Later, delete some items with -multiple, then with -multiple_key,
# TEST	and make sure if the correct items are deleted.
