OK -- I found out the following:

-- evince on linux renders the above doc ok, so it seems a FreeBSD
specific problem

-- evince on FreeBSD renders many other huge .pdf files ok, so it seems
specific to that kind of document

-- evince on FreeBSD renders a .ps version of the above doc
(http://beige.ucs.indiana.edu/M743/M743.ps.gz) ok, so the
problems seems with rendering certain .pdf files

So what is so specific to that document?  That it has type 3 fonts?
