Hi.
We have two properties ("prop1", "prop2") that references the same object
in this way:

***************
obj.prop1=createObject("myobject")
obj.prop2=obj.prop1
***************

When we are destroying the object "obj", we need to know who has been the
creator of the object "myobject". Are there any differences between
"obj.prop1" and "obj.prop2" for solving this question.

Thanks.
