Yes. I found them useful too but some people (including Andrew ;) 
were too argumentative about it so i asked you to remove them from 
this patch-set. So yes, it's all going the way of the dodo.

And yes, i attribute the excellent stability of the x86 code in this 
cycle partly to the effect of impact lines. They really helped us be 
very conscious with dangerous changes.
