As I mentioned in the LLD performance thread I'm aware of Vtune that
does that (if you have a license for it). It has also a very nice
'lock analysis' feature that might help in this case.
That said, I vote for getting the very first version you proposed in
the tree and refine things later, unless there's strong opposition. No
particular benefits of regression were found, but the patch I built on
top of it (linked in the other thread) showed up a significant
benchmarks for my use case.
