I agree with you about needing a list of reference count effects, but I
think the tutorial is otherwise about as clear as it could be on the
subject.  It's just a boring, unavoidably complex topic, and my eyes
would have just glazed over if someone had tried to carefully explain
the issues Bernhard raised before I had written that code.

I was thinking it ought to be possible to write a script that would pull
the signatures of the API functions from the docs, and write some C code
to determine their refence count effects.  You might be able to get a
long way to the sort of table we need that way.
