So why the need for + dataWithBytesNoCopy:length:freeWhenDone: ?
It would seem that if freeWhenDone is YES, these are identical calls?

Because sometimes you might want to use NO. i.e maybe its a non- malloced buffer that you want to treat as NSData, or maybe just a malloced buffer that you need to pass to some method that expects an NSData, but you don't want to have to duplicate the entire buffer.
