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'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!.
