CircleCI's Docker implementations silently ignore --read-only flag

docker

#1
ubuntu@box166:~$  docker run -ti --rm --read-only busybox
/ # touch /test
/ # ls /test

Expected:

/ # touch /test
touch: /test: Read-only file system

The same thing happens on Docker version 1.8.2-circleci-cp-workaround, build 4008b9c-dirty as well as Docker version 1.10.0-circleci, build 543ec7b-unsupported.
