Maybe the question should have been answered by adding a comment to the previous patch that added the `exit(3)` statement.

So yeah we could here add a separate patch that just adds such a comment.

Or maybe we can add such a comment in this patch and say something like "while at it let's explain a bit the '3' error code" in the commit message.
