[issue23103] ipaddress should be Flyweight

[Josh Rosenberg]

Josh Rosenberg added the comment:

What is your proposal? WeakValueDictionary mapping raw bytes object to single instance of ipaddress that is queried from ipaddress's __new__? No built-in has quite that extensive a level of caching and aggressive deduplication to my knowledge.
