I took another look at this particular thing, even though it's out scope of this PR. Apparently, the sole purpose of this dance is to make sure that `TranslationUnit` doesn't die before `Type` or `Cursor`. I have a feeling we can do better (read "less confusing"), but I don't have a concrete proposal yet.
