I'm curious about the results under the section titled "Demonstration."
The author claims that ground truth is that each goroutine utilizes 10% of the CPU time (so stipulated that this should be the case). But, what if the results shown are accurate, i.e. that the results are the actual CPU time (because of idiosyncrasies of scheduling between the OS, the go runtime, and anything else happening on that system).
Does running the new profiler show less variance in the results from that initial experiment? Showing this result would strengthen the claim that the "out of the box" solution is inaccurate.
