1.  At the end of each section, write the number of the last page to an
external file
(This is using plain TeX, I don't know how it would look in LaTeX)

\outer\def\bye{%
% front matter has negative values in \count0, otherwise \count0 is
set up for next
% page.  \endpage was set by reading endpage.tex at start of this
run.  See below
\ifnum\count0 > 0 % Don't bother with front matter
\message{doing blank page}\fi % blank verso page if needed
\openout\endwrite=endpage
\ifnum\endcount=\endpage \advance\notecount by -1 % was set up for
next note
\message{====lastpage=\the\endcount    ====lastnote=\the\notecount}%
\else\message{END PAGE NOT CORRECT--RUN AGAIN}\fi
\write\endwrite{\noexpand\endpage=\the\endcount}%
\fi
\supereject\end}

2.  Rerun if necessary.

3. Read the external file at the start of each run, and set the value of
\the\endpage where you need it.  Notice that even if endpage.tex doesn't
exist, TeX won't choke.

\else
\closein\endread % reset input pointer to start of file.
\input endpage
\fi
