Thanks for the ideas everyone--I now have some news tools in the toolbox.
The task is to use pdflatex to compile a bunch of (>100) chapters and know
when the book is complete (i.e. the book pdf is done and the separate
chapter pdfs are finished. I have to wait for that before I start some
postprocessing and reporting chores.
My original scheme was to use a class to manage the builds with threads,
calling pdflatex within each thread. Since pdflatex really does need to be
in the directory with the source, I had a problem.
I'm reading now about python's multiprocessing capabilty, but I think I can
use Karthik's suggestion to call pdflatex in subprocess with the cwd set.
That seems like the simple solution at this point, but I'm going to give
Cameron's pipes suggestion a go as well.
In any case, it's clear I need to rethink the problem. Thanks to everyone
for helping me get past my brain-lock.
