 In my opinion, the setter created by rb_objc_define_kvo_setter should
 check if the user might have overrided the regular Ruby writer method and
 call it.

 Consider:

 {{{
 class Foo
   attr_accessor :bar

   def bar=(value)
     @bar = 'bar'
     # super # depending on the impl.
   end
 end

 f = Foo.new
 f.bar = "foo"
 f.bar # => "bar"
 f.setBar("foo")
 f.bar # => "foo"
 }}}

 The user will expect the value to always be "bar" as defined in the #bar=
 impl.
