Interpreting multiple lines on one level of ProfileView

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?

@tim.holy I wasn’t sure where to ask this question; I’m hoping this works.

It means those calls were inlined by the compiler. Probably should be added to the README!
