I found a few places that manipulate ob_refcnt directly without worrying about 
keeping _Py_RefTotal or other debugging information in sync:

* classobject.c:instance_dealloc(), for __del__

* stringobject.c, for interned strings

* typeobject.c:slot_tp_del(), for __del__ too

I bet you could also find these easily, but maybe it should be regarded as a 
bug list.  At any rate, the __del__ tricks will indeed make some counters 

A bientot,
