1. Reap deleted/unused tuples on page-base 2. Reap unused tuples too 3. Reap empty pages 4. Check if a page is initialized, initialize it if not    and reap it 5. Binary search in list of reapped pages/tids to check    is the heap' tid pointed by a index' tuple on this list    (it's mu-u-uch faster)
