------- Additional Comments from Darin Adler <darin at apple.com>
This is unnecessarily fragile. While it's true that a document can reach the
state where its true refCount is 0 and the only references keeping it a live
are the self-only references from its children, it's not at all guaranteed that
this state corresponds with the case you care about here. I know you're looking
for "the right check" to detect this bad situation, and sadly this is not the
one.

I'd like to understand exactly what makes the document "bad to work with" here.
Then I can help you figure out the right way to code it.
