$unlink infinite recursion

[Paul Spencer]

Hi,
I've filed a ticket (#346) in lighthouse for this, but I thought  
perhaps others might be running into this as well and would appreciate  
a heads up.

You can easily cause an infinite recursion using setOptions if you  
have circular references in objects passed as options.

window.addEvent('load', function(){
    var a = {};
    var b = {};
    b.a = a;
    a.b = b;
    new C({a:a});
});
var C = new Class({
   Implements: [Options],
   options: {
       a: null
   },
   initialize: function(options){
       this.setOptions(options);
   }
});

I've tried quickly to fix this but $unlink is not for the faint of  
heart and I haven't had any real success yet.  Actually, this is the  
first time I've reduced this to a simple test case so perhaps I will  
have more luck now :)

Cheers

Paul
