# Ensure a full vacuuming run deletes records
# Create some records, delete some of them on their lmaster (with a
# test tool that doesn't do SCHEDULE_FOR_DELETION), run some fast
# vacuuming runs (to ensure they don't delete records that haven't
# been added to the delete queue) and then try a full vacuuming run,
# which will actually do a traverse of the database to find empty
# records and delete them. Confirm that records that haven't been
# deleted are still there, with expected values.
