Brainstorming here. We could choose to always expose resonseArrayBuffer  
and keep it together with responseText and responseXML. And for  
applications that are worried about memory usage or care about very large  
files we could have BlobXMLHttpRequest similar to AnonXMLHttpRequest. We'd  
abstract some things out from XMLHttpRequest so BlobXMLHttpRequest does  
not have the other response* members and so that AnonXMLHttpRequest does  
not need withCredentials and the fourth and fifth parameter to open().
