NSTextStorage is an NSAttributedString subclass, and the docs of - 
[NSAttributedString string] says the following: "For performance  
reasons, this method returns the current backing store of the  
attributed string object. ... This primitive method must guarantee  
efficient access to an attributed string’s characters; subclasses  
should implement it to execute in O(1) time."
So I believe it's fast enough. I haven't seen any performance change  
on my macbook.

What is broken? This is a new feature, not a bug fix.
