Problem description on golang-nuts:
https://groups.google.com/d/msg/golang-nuts/mWXsJJMdL0M/wioVT04ye7UJ

In short, pprof misses 7.5% of samples in newstack/oldstack (perf reports them
properly). This happens because the profiler ignores samples on g0 (where
newstack/oldstack are executed). We need to figure out a way to attribute the samples to
the running goroutine.
