In a thread elsewhere, trying to analyse why the zfs auto-snapshot
cleanup code was cleaning up more aggressively than expected, I
discovered some interesting properties of a zvol.

The zvol is not thin-provisioned.

This is as expected. Not expected is that:

I would expect this to be 0, since all the reserved space has been
allocated.
This would be the case if the volume had no snapshots.
As a result, used is over twice
