Was there a v1 for this patch?

You do this a few times, so perhaps add a helper to create a simple
simulator with a given a number of lines?

(I called the equivalent in my tests a Simpleton, borrowing LinusW's
practice of naming things after yourself.
Not that I'm suggesting you use that name.)

And rename make_sim() to make_sim_builder(), as it the build() that
returns the sim?

Cheers,
Kent.
