Good point... although doesn't the page optimization feed back into
paragraph layout?

Sounds useful. It's impressive if you can get "a correct table of
contents in the first run" (says

But this is just a problem of typesetting with TeX in general, not
particular to parallel/distributed typesetting, right?
IIRC, Knuth even says in the TeXbook that a really pathological case
might never stabilize.
