Mount a Docker volume to /nix when running
docker-testscripts
to speed up tests. Also setXDG_CACHE_HOME=/nix/cache
so that the tarball and eval cache persist to the volume. UpdatesetupTestEnv
to share the pip cache between tests (the same way we do with Nix's cache).This cuts the duration of python linker tests in half (down from about 1 minute to about 30s).
