Is there a way for Drone to run multiple builds on the same machine in parallel?

I have tried by adding:  
DRONE\_WORKER\_NODES=unix:///var/run/docker.sock,unix:///var/run/docker.sock  
to Docker-Compose but it didn’t work

Drone version 0.7

You can specify `DRONE_MAX_PROCS` environment variable on agent and set to number of builds you’d like to run in parallel. By default it is `1`.

Do you know the difference if compare to set DRONE\_MAX\_PROCS to 2 in one drone agent and start with two drone agents? They both can run two builds at same time.
