I must have hit the 0.1% chance. The debian/fontconfig.postinst says:

if [ "$1" = configure ]; then
  # (Hacked up from Red Hat 8 fontconfig RPM)
  # Force regeneration of all fontconfig cache files.
  # The redirect is because fc-cache is giving warnings about ~/fc.cache
  # the HOME setting is to avoid problems if HOME hasn't been reset
  printf "Regenerating fonts cache... "
  HOME=/root fc-cache -f -v 1>/var/log/fontconfig.log 2>&1 || (printf "failed.\nSee /var/log/fontconfig.log for more information.\n"; exit 1)
  printf "done.\n"
fi

and I'm sure I saw the "Regenerating fonts cache... " line when installing.
I've seen this same slowdown on a celeron (as compared with my P4),
both running debian/testing so something really goes wrong with this
build.
I'll wait for the fontconfig-2.3.94 and report back ..
