-- Notes
--
-- 1) you may find that the allocated pages toward the end of files belong to
-- one or more system objects, in which case you can't rebuild/reorg them, so you
-- may need to shrink the files to move at least these and then resume from the next
-- non system object
--
-- 2) rebuilding heaps is not implemented, it's just a matter to add a CASE, I'll do it
-- the first time I have to so that I can test it
