There has been zero of my cycles spent thinking about this. Partially
because I'm busy in other areas, partially because I know Daniel is
planning changes in libvirtd
(https://www.redhat.com/archives/libvir-list/2018-May/msg01307.html),
and partially because I'm not sure I have a {reliable|simple} reproducer
(at least I don't recall).

I do still have various branches in various states of disarray that are
way behind current head (easy to happen it seems lately).
