# TEST test038
# TEST DB_GET_BOTH, DB_GET_BOTH_RANGE on deleted items
# TEST
# TEST Use the first 10,000 entries from the dictionary. Insert each with
# TEST self as key and "ndups" duplicates. For the data field, prepend the
# TEST letters of the alphabet in a random order so we force the duplicate
# TEST sorting code to do something. By setting ndups large, we can make
# TEST this an off-page test
# TEST
# TEST Test the DB_GET_BOTH and DB_GET_BOTH_RANGE functionality by retrieving
# TEST each dup in the file explicitly. Then remove each duplicate and try
# TEST the retrieval again.
