I changed the comment -- see attached patch.


> The concept here is to aggressively prioritize scheduling for latency in PostRA mode—unless the unscheduled instructions are clearly resource limited. I agree with your comment. Not sure what your question is ;)
That's actually making sense to me now - sorry. I was confusing "policy" 
and "candidate evaluation".
