No, I think it should do nothing. The coding pattern shown in bug #9464
seems perfectly reasonable and I think we should allow it. No doubt it's
safer if the child process does an on_exit_reset; but right now, if the
child fails to do so, atexit_callback is actively breaking things. And
I don't think we can rely on third-party libraries to call on_exit_reset
after forking.
