Is it so common to write books in a single monolithic file ? The two
typesetting systems I use from emacs allow (and encourage) to split the
documents in many files. And emacs corresponding modes are designed for
easy navigation between them.

That said, I totally agree that this is a real concern : what happens if
someone wants to _open_ a huge document. As Lennart said, it probably
isn't the job of the display system to restrict the data to render to
a subset, but rather the job of an intermediate layer, between the
document and the rendering engine.
