Which raises the question, what is acceptable? I don't think
a 10% gain in itself is worth gzipping PDFs for. If 10% was
the "threshold", bzip2 should be used instead of gzip for
other things in /usr/share/doc.
I think PDFs use ZIP internally. ZIP has compression ratios,
perhaps PDFs can be re-packed to use a higher ratio?

How random? You can't adequately compress noise.
