The aim here is to avoid exhausting RAM of our normal machines on hydra.nixos.org. See #227945 for details.

Well, it's not ideal, e.g. https://hydra.nixos.org/build/217914128#tabs-buildsteps was on a big-parallel machine and it was thrashing a lot, but at least it completed within an hour. We'd just need some machine with more RAM. (just 64G total for this one... and using /nix/store in RAM with swap on disk)

We might still be in trouble in case two tarball jobs align on the same machine in the most expensive phase.
