WDYT? We shouldn=E2=80=99t compromise reproducibility for parallel builds. Ideal= ly we would figure out what exactly causes the differences and fix that instead of disabling parallel builds, but if that turns out to be too difficult I think we should just revert this until we have a good fix. Perhaps something can be done by fixing the order of files somewhere. --=20 Ricardo
