Just a note, if someone actually depends on this: it is not true in
all cases. For example, in CPython 3.5.3:
>>> class X:
... __slots__=() # <= note this!
... def __del__(self):
... print("DEL")
... global resurrect
... resurrect = self
...
>>> print(X())
<__main__.X object at 0x7f5d1ad600d0>
DEL
>>> resurrect=None
DEL
>>> resurrect=None
DEL
>>> resurrect=None
DEL
A bientôt,
Armin.
