While working on this file it seemed odd to me that this one env variable
is not in the .travis.yml "env" section. It makes sense to group it here, too,
because in the future we might find that some tox envs run fine with
multiprocess. (The Travis VMs/containers all have 2 cores, actually. I still
don't know why are our tests fail when we switch to 2 processes.)
