If at all, I think it only makes sense if a file vanishes on its own,
thus freeing space.  If nothing ever accesses it, it will forever use up
space.

But then, I don't think that filesystems should become "to intelligent"
and tinker with their content on themselves (with maybe the exception of
some filesystems that are designed for this, devfs, ptyfs etc.  /tmp is
none of these and should best be left alone, imo)
