Subject: Does "rescue" wihtour argument handle any kind of Exception or not?

Hi, I read in this article:
  http://jerith.livejournal.com/40063.html
that:

---------------------------
Exception
  - StandardError
    - RuntimeError
    - ZeroDivisionError
  - ScriptError
    - SyntaxError
  - SystemExit
  - SignalException
    - Interrupt

The important bit there is that all the stuff you can reasonably expect to 
recover from is under StandardError. Because of this, a default rescue block 
will not catch anything that isn't a StandardError. The observant reader will 
notice that I helpfully showed Interrupt's position in the hierarchy. The 
observant reader will also notice that it is not a subclass of StandardError. 
This means that you need to catch it explicitly, or it will cause a crash.
---------------------------

But is it really true? I do:

----
begin
	raise Interrupt
rescue
	puts "rescued !!!"
end
----

And I get:

=> "rescued !!!"


So is the above article tru or not?

Thanks.
