ACK. Thanks to patch 2/6, you could now technically close the connection first, then unregister the callback, and the reference held by the callback will ensure that the connection lives long enough to let that work even after things were "closed". Most likely to happen if things are multithreaded, where one thread is unregistering while another thread is closing the connection. But given that earlier libvirt had problems, we obviously don't want to advertise that "backwards" approach to cleanup. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
