I am tracking Peter's code in tip/core/locking: c10b491: mutex: implement adaptive spinning, v8 c356a7c: mutex: implement adaptive spinning, v7 b89e5d8: mutex: implement adaptive spinning, v6 237ac94: mutex: implement adaptive spinning And v8 is rock solid in all my testing - and i'll give v10 a similar workout as well. Would you prefer a single commit or is this kind of delta development history useful, with all the variants (at least the later, more promising ones) included? The commits are in a tight group with no merges inbetween.
