Thanks.  Of particular importance is the leela change.  My recollection 
was that the f-m-o work also picked up that case.  But if my memory is 
faulty (always a possibility), then that shows a clear case where 
Jivan's work picks up a case not handled by Manolis's work.

And on the other direction we can see that deepsjeng isn't helped by 
Jivan's work, but is helped by Manolis's new pass.

I'd always hoped/expected we'd have cases where one patch clearly helped 
over the other.  While the .25% to .37% improvements for the three most 
impacted benchmarks doesn't move the needle much across the whole suite 
they do add up over time.

Jeff
