As much as I'd like to see that happen based on discussions so far its unclear
if this is going to be possible unless strong commitment is reached... so what
this tried to do was to take the other way around the problem, by slowly
shifting out junk. Although I'm frankly new to this -- I think this approach might
be more feasible over time. As I see it this is an extension to Al's original
commit 0ee5dc676 but more in line with how they are really are used and exposes
more information to the VFS. As it stands now other filesystems can pop up and
do similar things, this at least extends the original API to fit the use case a
bit more closely to how its used and allows more room to grow.
