* Pass `-j 1' to hydra_eval_jobs to ensure that it can make progress

even when all the remote build slots are in use.  The evaluator can
  cause builds if Nix expressions import derivations (e.g. in
  pkgs/build-support/vm to compute the RPM/Deb closures).  If there
  are no free build slots, the evaluator can hang for a long time.
