The constructor object is the same object that you created; that's why  
it has the same memory address.

When creating it, you can store any pointer you like in that object.  
You'd use the JSObjectSetPrivate function, and then get the value back  
with JSObjectGetPrivate.

I think that will be sufficient for what you're trying to do.
