This part of the API is only concerned with getting the snapshot properly
created. I'll talk with Heinz next week about how the new persistent
snapshots affect things, and how he is handling the updates.
As long as his ordering looks like this:
copy extent to snapshot, wait
update bitmap, wait
write extent
Things should be fine without any help from the journal layer, but it will
be slower than it could be.
