ACK for fixing the issues raised in v3.  There was a slight merge
conflict, but not serious.

I'm not pushing 8/8 (it really does belong more in libvirt-tck, once the
perl bindings catch up), so I think this series is now complete, other
than my ideas for enhancing virsh blockpull --all to take a --block flag
that waits for the event.
