[issue38006] Crash in remove() weak reference callback of weakref.WeakValueDictionary at Python exit

[Tim Peters]

Tim Peters <tim at python.org> added the comment:

Neil, how about this alternative:  leave the weakref implementation alone.  If we find a trash weakref, simply clear it instead.  That would prevent callbacks too, & would also prevent the weakref from being used to retrieve its possibly-trash-too referent.
