Just tie jobs to master that have dependencies there, and mark it for
tied jobs only, and let other jobs target labels if they have specific
OS/CPU requirements.

I don't think anything is particularly 'broken' at the moment is it?  I
was just trying to understand the current set-up, and if we ask new jobs
to set up a bit differently we can prevent over burdening master while
leaving spare capacity elsewhere.
