Currently we expect our size after cleanup to be 98k for the current
database schema and page sizes and constants used in this test. We
set the threshold at 128k so the test doesn't start failing if these
control objects/structures increase somewhat in size, but should still
fail if we fail to delete all of the 5,000 1k files we create on disk
as part of the test.
