I have had the pleasure to debug refcount reference overflows and let me 
say it is not something I would like to repeat since it happened only on 
32 bit test systems (the count would also wraps on a 64 bit box, but 
that would take a while longer). So I would highly suggest to fix any 
reference count leak since you never want code to crash for stupid 
reasons like this.
