To the best of my knowledge, Filling volumes are subject to reclamation
just as much as Full volumes are: it's just a matter of the combined
size of the "holes" in the volume's thus-far-written area.  Remember
that there's no guarantee that you will never have more than one Filling
volume for a given stgpool: multiple processes may cause there to be
multiple volumes in Filling state.  This can eventually cause a Filling
volume to be just hanging around, unused for a long time; and the Filling
volume could be 98% written.  You want such stuff reclaimed.
