The documentation of MSXML's IXMLHttpRequest abort method
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/7b1cfc92-5078-404a-85a2-a907fe1184a2.asp>
also says:
   "The request will be returned to the UNINITIALIZED state"
and
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/0e6a34e4-f90c-489d-acff-cb44242fafc6.asp>
defines UNINITIALIZED as 0.

Why does Mozilla do a 4 to 0 transition with readyState, why does it not 
directly go to readyState 0?
