That doesn't answer my question.  Gecko fires only one readystatechange 
event to switch to LOADING: it's fired when we get the first "data 
available" notification.

What you're proposing is that in some cases we NOT fire this event when 
we get the first "data available" notification, but I can't tell what 
sort of cases these are.
