IMO, total_free_space() and available_free_space() should be tied
together so that you can make some relationship between them. If they
are implemented as separate calls, then you don't really know what disk
activity went on between the first and second calls. I can see a case
where the total_free_space might be < than the available_free_space if
you called the functions in the wrong order and there was disk activity
going on.
