Well, I haven't looked at the code specifically, but it only makes sense
that it would read and parse the entire file first. After all, it needs
to make sure the file is syntactically correct before it trusts anything
in it, e.g. what if it finds a *second*, illegal SOA record further into
the file? Which of the two SOAs would it trust?
