I think the PEP should also specify what will happen if the generator's __next__() method is called again after RuntimeError is handled. The two choices are: 1. Raise StopIteration (current behavior for all exceptions). 2. Raise RuntimeError (may be impossible without gi_frame). I think choice 1 is implied by the PEP.
