Description Alexey Proskuryakov 2005-12-03 06:44:03 PST

If the response to XMLHTTPRequest is zero-length, not all onreadystatechange events do fire, and the 
response headers aren't properly retrieved.

Steps to reproduce: access the bug URL.

In MSIE, the request goes through all states. Firefox skips Interactive. WebKit skips Interactive and Loaded.

Even in Completed state, WebKit doesn't provide the headers or the response status.

This looks totally fine.  You're just changing slotFinished to match slotData's
behavior in the case that slotData was never called.  r=me
