[issue16822] execv (et al.) should invoke atexit handlers before executing new code

[Antoine Pitrou]

Antoine Pitrou added the comment:

That's a good question. Conceptually it makes sense, but I wonder if programs currently rely on os.execv not cleaning up anything: not only it doesn't call atexit handlers, but it also doesn't try to shutdown the interpreter. Which can be handy if you are using exec() in a fork() + exec() context (I think it is generally recommended to use os._exit(), not sys.exit() in a forked child).
