# [OS X TeX] 'Too many open files' error with pdftex

When I run pdtex on a file with a large number of PNG figures, I get
a 'Too many open files' error.  Looking through the archives for this
list, I found the following work-around:

\let\mypdfximage\pdfximage
\protected\def\pdfximage{\immediate\mypdfximage}

BUT: using the above trick doubles the size of my (already too large)
output PDF file.  Presumably all the graphic files are being included
twice.

Is there another way to avoid the 'Too many open files' bug?

(I'm willing to recompile pdftex if someone would tell me how to
reconfigure or patch it.)

Thanks,

Kevin
