I don't have a strong opinion, either - it doesn't matter what it is
named if no one outside of qtest uses that name :)  When developing
libvirt interfaces around new actions, I might use an abort to
intentionally test behavior of libvirt error-handling code, but that
would still be something I do by hand (by any name) and not something
coded into libvirt itself.
