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.
