This is the paragraph after the one you replied to above:

The remainder of my message then goes on to describe a hierarchy just as you 
suggest - SystemError, MemoryError, StopIteration and GeneratorExit are all 
still caught by "except Exception:". The only two exceptions which are no 
longer caught by "except Exception:" are KeyboardInterrupt and SystemExit.
