What Gecko version?  Gecko 1.8.x doesn't do DOMSubtreeModified.  Gecko 
1.9 will.

Well....  Not necessarily.  Per spec, DOMSubtreeModified can fire only 
once per multiple changes.  That's one of the reasons it wasn't 
implemented before; it's not clear what a "correct" implementation is.

In Gecko 1.9 we do coalesce mutations somewhat in some cases, as I recall.
