Description:
------------
During unserialization of a 3 deep non-recursive but not-a-tree data structure (more like a diamond) where, on nodes in level 2 a __wakeup causes all references to a child node of a certain class to be removed, when that child node would occur in subsequent level 2 nodes' child spots, the reference instead now points to the next level 2 node instead of any level 3 node.  More specifically, it points to the first level 2 node after the one that removed said child.

The sample code makes it more clear.

Reproduce code:
---------------
	class B {
		public $value;
		function __construct($value){ $this->value = $value; }
		
		function __wakeup()
		{
			if($this->value instanceof C)
					$this->value = C::$instance;
		}
	}
	
	class C { static public $instance; }
	
	C::$instance = new C;
	
	$A = array(  new B(C::$instance), new B(C::$instance), new B(C::$instance) );	

	var_dump($A);
	$A = unserialize(serialize($A));
	var_dump($A);

Expected result:
----------------
array
  0 => 
    object(B)[2]
      public 'value' => 
        object(C)[1]
  1 => 
    object(B)[3]
      public 'value' => 
        object(C)[1]
  2 => 
    object(B)[4]
      public 'value' => 
        object(C)[1]

array
  0 => 
    object(B)[5]
      public 'value' => 
        object(C)[1]
  1 => 
    object(B)[7]
      public 'value' => 
        object(C)[1]
  2 => 
    object(B)[8]
      public 'value' => 
        object(C)[1]


Actual result:
--------------
array
  0 => 
    object(B)[2]
      public 'value' => 
        object(C)[1]
  1 => 
    object(B)[3]
      public 'value' => 
        object(C)[1]
  2 => 
    object(B)[4]
      public 'value' => 
        object(C)[1]

array
  0 => 
    object(B)[5]
      public 'value' => 
        object(C)[1]
  1 => 
    object(B)[6]
      public 'value' => 
        &object(B)[6]
  2 => 
    object(B)[7]
      public 'value' => 
        object(B)[6]
          public 'value' => 
            &object(B)[6]
