I'd like to propose a enhancement to at_exit.
It would be nice if you could stop a at_exit handler from running in subprocesses.
You can do this manually with this code:

parent = Process.pid

at_exit do 
  if parent == Process.pid 
     # …
  end
end

You can also do it by bypassing handlers:

at_exit do
  # …
end

fork do 
  exit!
end

But it would be nice if I could do:

at_exit(false) do
  # …
end

The first approach is kind of ugly, and the second approach isn't sustainable if code outside
your control can fork(…) without calling exit!.

Matz, do you think this kind of feature is needed?
I guess you'll say, the argument should be a keyword option, at least.

at_exit(process_local: true) { ... }

I don't like this name. at_exit() is always process local. He hope to
make no subprocess inheritance option.
