But you don't want the files fragmented, either, as your database will
get much larger if it has to store a long list of fragment locations for
each file instead of just a single entry for it. Thus, reclamation _is_
desirable, in as much as it 'defrags' the volume. Especially since the
defrag algorithm in this particular case is very simple.
