I'm not sure the problem is so much that anyone wants to support resurrection in del, it's just that it can't be prevented.

Well, Java has an answer to that (at least I believe Tim Peters told me so years ago): it allows resurrection, but will only call the finalizer once. IOW if the resurrected object is GC'ed a second time, its finalizer won't be called. This would require a bit "del already called" on an object, but don't we have a whole word of GC-related flags?
