   I do not see how it is something the XHR spec can change - it's  
obviously an RFC 2616 domain, and RFC 2616 is very explicit in what it  
says about header name case insensitivity.

  We may or may not change the behavior to be compatible with other  
engines in this regard in the future. However, I am pretty sure that  
an official W3C test suite should not flag us with a "FAILURE" as long  
as we conform to the letter of RFC 2616.
