# TEST This is essentially test111 with the user-specified sort.
# TEST Populate a database. Remove a high proportion of entries.
# 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.
