in the commit message and squashfs-tools has had several updates
to it's
parallelism since this time. There are currently no open issues
related
to parallelism in their issue tracker:
https://github.com/plougher/squashfs-tools/issues
It now "works for me" with 16 threads, and while this is a
terrible test
for a race condition I still propose we remove this work-around
unless and until we have specific knowledge of a current bug.

Are the images still reproducible after that change?
If I remember correctly, threading would break that.

Hello. I'm not sure what you mean by the images being reproducible.
Reproducible means you can compile twice (or more) and it will result
in identical (bit by bit, same checksum) binaries every time.
Multithreading apparently broke that, as Felix stated. While
reproducibility might not be an issue for you personally, I believe
it's one of the project's goals - it's a way to ensure the builds that
are publicly available have not been tampered with.
