I'm not sure the problem is so much that anyone _wants_ to support
resurrection in __del__, it's just that it can't be prevented.
 l = []
 class A(object):
 def __del__(self):
 l.append(self)
 a = A()
 a = 1
What would you have this do?
And if we want to have a version of __del__ that can't reference
'self', we have it already: weakrefs with callbacks. What happened to
the 'get rid of __del__ in py3k' idea?
Cheers,
