-------------------------------
Sorry [~eepayne] for the delay here.
Yes, it makes sense. I was looking for one more metric earlier where I can get
an idea that how much preemption happens over a time. But its not needed very
much and lost cycles is more critical for cluster.
I am fine with latest patch. If no issues, I could commit this patch.
