KeyboardInterrupt can also be raised at (effectively) any time, but
I'm not sure that that really counts as id() raising the exception. If
I understand it correctly, MemoryError would be because the
interpreter can't allocate an int object for id's return value.

But these are definitely part of why you don't just catch all exceptions.

Hmm. What happens if the interpreter can't construct a MemoryError exception?
