Nit: instead of checking for `BISECT_START` we should rather check for
`BISECT_TERMS`. Like that we don't waste two processes for users who
didn't specify any terms, which should be the majority.
We could also parse the terms directly from the file... but I'm not sure
that is really worth it and feels a lot more fragile to me. So I'm not
sure whether or not that is a good idea.
