Ah, we are compiling C in a special way to see this with the
tool later.

What one should do then is run it for 100 hours for 100 Emacs
users' arbitrary Emacs use, then we would see what everyone
was up to in the C part as well.

Some would say even slow C is pretty fast but as we just saw
even that can be improved a lot actually ...
