I finally got a bit of time to work on this. I'm confused about how the
tools will take care of this at the moment. How much support currently
exists for these sorts of weighted samples? The only thing I can find
that looks related is PERF_SAMPLE_READ, but I don't think that's exactly
what we need.

Could someone point me in the right direction?
