I think millstone is being oververbose, and it also has a way to skip but we are not setting the variable it uses for that.
Variable in use being https://github.com/mapbox/millstone/blob/v0.6.11/lib/millstone.js#L12
if I understand correctly just setting the NODE_ENV environment variable to something different from "development" hushes it. I'm not sure this is something that should be done by grainstore itself, probably not. \cc @lbosque @rafacas
Yep, I won't do here
