# TEST	Use the first 10,000 entries from the dictionary.  Insert each with
# TEST	self as key and data; add duplicate records for each.  After all are
# TEST	entered, retrieve all and verify output using DB_GET_BOTH (on DB and
# TEST	DBC handles) and DB_GET_BOTH_RANGE (on a DBC handle) on existent and
# TEST	nonexistent keys.
