FYI, this change exposes a bug in the atexit module involving subinterpreters, causing the refleaks reported by Antoine's daily report: interpreter startup now always imports weakref, which imports atexit and registers a classmethod. Unfortunately the atexit module doesn't seem to know subinterpreters from subtitles and so doesn't unregister this classmethod when the subinterpreter is terminated. This isn't a new bug, but it's exposed by always importing weakref and atexit during interpreter startup. I'm wondering if that's really necessary :)

Is there an issue tracking this?
