Thanks Cory! That clears a major worry (regarding the speed of vacuuming a large database with a large number of records deleted) in my mind. Temporarily, letting the database take up extra space is not a worry, so we'll just leave it in the records deleted state and let SQLite reuse the memory as it goes along.
