⁠SHM Size fix

If you get unexplained behaviour you may need to increase the SHM Size , bad behaviour could include odd things happening when opening a new window etc.

Try adding the shm_size parameter.

  selenium-chrome:
    image: eksponent/selenium
    ...
    shm_size: 2gb

You will need 1.7.0+ to use this argument, if you're running from CircleCI..

machine:
  pre:
    # 1.7.0-beta onwards supports shm_size
    - sudo pip install docker-compose==1.9.0 -q
