Isn't this mostly political correctness? The hello world programs really don't need to worry about closing the socket pair. Most real-world programs don't either -- the recommended pattern is just to loop until the end of the world, and then exit the program.

I'd like to counter with some political correctness of my own -- this smells like a new feature and therefore shouldn't be added to 3.4.  (Adding Larry -- if Larry is fine with making small additions to asyncio during the beta, I am also okay with adding this.)
