Index generation, cross references, things like that (pagination
decisions are taken at the latest possible moment, so references
to the current page (number) and more so references to following
pages are not resolvable in the first pass. If you're nasty, a
page break might depend on the width of a not-yet-known page number
which depends itself on... you get the idea).

Other things potentially needing more than one pass: long tables
spanning several pages.

Dvi workflow is pretty minimal, and I love it when I can get away
with it. OTOH, pdflatex (and lualatex) have tricks which the more
traditional workflow can't play.

For some examples, go browse http://www.texample.net

Sometimes, a good visualization is worth a lot.
