I wonder why #:parallel-tests? defaults to #f in ‘meson-build-system’,
contrary to what other build systems do.

I think we should create a branch where we change it to #t, and merge it
once we’re done rebuilding all the packages and fixing any relevant
failure.

Would you like to give that a try?

Thanks,
Ludo’.
