Job assignment approach to build agents

I’m using Drone v0.5 with one server and >10 agents. I’m wondering how jobs are assigned to (or picked up by) build agents if I don’t have DRONE_MAX_PROCS set. Is it round robin or something else? It wasn’t clear by looking at the logs, so is it something I’m missing? Let me know if you need anything else.

@brad could you pls clarify???
