 NSKeyedArchiver fails to find a superclass's implementation of
 'encodeWithCoder:'
 when its objects are encoded in a particular order.  When the code
 excerpted
 below is run:

 {{{
 class ArchiverDelegate
   def archiver archiver, willEncodeObject:object
     puts "willEncode #{object.class}"
     object
   end
 end

 def test_archiver
   graph = Graph.new

   a = A.new
   graph.addNode a

   b = B.new
   graph.addNode b

   b.connect a

   data = NSMutableData.alloc.init
   archiver = NSKeyedArchiver.alloc.initForWritingWithMutableData data
   delegate = ArchiverDelegate.alloc.init

   archiver.setDelegate delegate
   archiver.encodeObject graph, forKey:'root'
   archiver.finishEncoding
 end

 10.times do |i|
   puts i
   test_archiver
 end
 }}}

 I get results such as this:

 {{{
 $ macruby test-archiver.rb
 0
 willEncode Graph
 willEncode NSCFSet
 willEncode A
 willEncode B
 willEncode Connection
 1
 willEncode Graph
 willEncode NSCFSet
 willEncode B
 willEncode Connection
 willEncode A
 /Users/ehynes/ClockSmith/current/Test/hgignore/test-archiver.rb:1:in
 `<main>':
  super: no superclass method `encodeWithCoder' for #<A:0x2000cc160>
 (NoMethodError)
 }}}

 The NoMethodError occurs whenever B is encoded before A.  Attached is the
 complete code example.
