# TEST test113
# TEST Test database compaction with duplicates.
# TEST
# TEST This is essentially test111 with duplicates.
# TEST To make it simple we use numerical keys all the time.
# TEST
# TEST Dump and save contents. Compact the database, dump again,
# TEST and make sure we still have the same contents.
# TEST Add back some entries, delete more entries (this time by
# TEST cursor), dump, compact, and do the before/after check again.
