I'm not yet persuaded about the need for this change.
The aim is that the behaviour of the tools be consistent across
the whole command set.
Waiting for the operation to complete feels more intuitive to me.
(It's the existing cases where we don't wait for the kernel to
finish its initial copy that feel wrong to me.)
