Memory leak when assigning object to property (circular reference)

[felipensp]

class Foo {
    var obj;

    function Foo(z) {
        this.obj = z; // causes the memory leak
    }
}

class Bar {
    var arr;

    function test() {
        this.arr = [];
        this.arr.append(Foo.new(this));
    }
}

var b = Bar.new;
b.test();

That is going to happen until we replace our RefCount model to a garbage collection like mark and sweep or copy collection.
