Exactly that, the snapshot deletion only "syncs" on unmount, there is no
other way to ensure it is complete.
If you have some patience and let it unmount properly and then remount it, you
may find that you have gained much more free space, due to all the snapshots
being actually deleted and the space they were occupying freed only just now.
