A handy feature of ProfileView is that hovering over the graph shows the line that goes with the bar one is over. However, for some of my results, I see multiple lines listed. What does this mean?

It means those calls were [inlined](https://en.wikipedia.org/wiki/Inline_expansion) by the compiler. Probably should be added to the README!
