Each<domainsnapshot>   can now contain an optional<memory>
element that describes how the VM state was handled, similar
to disk snapshots.  The new element will always appear in
output; for back-compat, an input that lacks the element will
assume 'no' or 'internal' according to the domain state.



So for 0.10.2, I plan to implement this table of combinations,

1.0.0, now (I'm assuming that this part of the series is worth pushing
for 1.0.0, even though Peter's series missed the rc1 freeze date)...

Does anyone else have arguments on whether the rest of this series
should be in or out of the next release?

I think it's safe to push.

and another instance.
