Worker output not streaming quite right

[JScott]

commands:
- git-sync [email protected]:JScott/robot_sweatshop.git
- rake test

This is a thing that takes a long time and will fail a lot (because Robot Sweatshop is already running!). I was really confused to not see output for a long time because it should be streaming line-by-line. It wasn't, for whatever reason, but it should.
