Avoid stack exhaustion in superclass_names() #175

  1. Avoid stack exhaustion in superclass_names()

    Because this function is recursive, it can exhaust the stack if the
    class hierarchy contains duplicate names. Avoid that using simple
    memoization.
    
    Also, these two supporting functions can be classmethods because they
    don't use any instance-level state.
