Hmm, when doing a pull-mode backup, do we ever want a write-threshold on the
temporary image?
That's a good question. I didn't yet have a request for it.
Or is this only for actual block-copy mirroring, and not
backups?
This one is just for block copy for now. The slight problem is that the
backup scratch is not associated with the disk in the VM xml, but
technically nothing prevents us from adding the event for that as well.
The question is only how to do it API-wise.
