Some of my notation choices were over specific, selecting just directories.
More complete is:
# du -sm
/usr/local/poudriere/data/.m/main-CA76-bulk_a-default/*/portdistfiles/* | sort
-rn | head
9253
/usr/local/poudriere/data/.m/main-CA76-bulk_a-default/09/portdistfiles/electron

/usr/local/poudriere/data/.m/main-CA76-bulk_a-default/10/portdistfiles/blender-4.2.0.tar.xz
. . .
(The 2nd chromium is ungoogled-chromium.)
So for the first 7 of those: somewhat over 37 GiBytes of tmpfs
use in an overlapping overall-time-frame, just for the portdistfiles/
contributions.
