I think your changes make sense (and the graphical benchmark does look
better). However, I think we should scrap that pie chart and just create
a table with information, sorted by the order in the array. That way we
can visualize the code paths and see the difference in time between one
point and the next.
I'll accept patches for 1.5.2 on this :)
