[issue42466] asyncio loop.getaddrinfo raises RuntimeError

[Andrew Svetlov]

Because it did work in a gray area.
The finalization logic has slightly changed, some tricks that were working before now fails.
Sure, other undocumented tricks start working :)

The rule of thumb: please stop and close the asyncio loop before exiting the program. This rule allows for avoiding situations like this.
