Yes, we can add "events" handling to -prof perf. It was not added before, because most users are
fine with -prof perfnorm. Please hack up the patch, if you are willing. If not, I'd get around to it

On the up side, after our OCA is accepted, you can contribute changes to every other part of OpenJDK.
