This is the one that gets my vote. It's trivial, it fixes a general problem
not just incorrect unwind behaviour, and (if I remember right) the
additional overhead was tiny. (It could be made unmeasurably small by
specialising local and non-local returns, instead of them both sharing a
common "return: value to: context" in the Interpreter.)
