Bug: sometimes the follow output does not work

[chuckha]

I'd like to be able to follow the output of a build step. Right now I guess I have to push j a lot or PageDown is probably better...but having a follow would be neat.

Edit: this normally works, but there is an edge case

Steps to reproduce

This notes.mill file:

sh("rm sonobuoy", tolerate_failure=True)
sh("make container IMAGE_VERSION=test VERBOSE=true")

on this repo https://github.com/heptio/sonobuoy

I think some combination of docker and go build -v is causing the follow to not work.
