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