I don't have any justification for this except an empirical one: with this patch the code from Bug 1363628 doesn't crash after "leaking". I currently don't have properly working valgrind, but I'm working on it and it might shed some light into this (although it might also not happen due to the slowdown). However in the meantime I attempted some analysis and I got even more confused than before, I guess. With this patch the code doesn't crash, even though virObjectEventStateQueueDispatch() properly skips callbacks marked as deleted. What I feel is even more weird, that if I duplicate the purgatory function (instead of moving it), it crashes again, and I feel like even more often.
