I left this running in a loop to throw an error if weakRef's value is ever
nil and so far it hasn't happened in several hundreds loops yet (it's slow
because of the full GCs). This makes me wonder if you are using some kind of
custom VM that you've built yourself - what platform, what VM *are* you on?
