I suspect this is not directly related with it, but more with the issue we have had with perf reproducibility last week. So I dropped this patch for now, but I will take it a bit later this week and try to go further. I still wanted to provide some feedback here. Also, if anyone believes this issue IS related with this series, please share your thoughts.
