so I have 1GB of RAM to play with yet docker stats is reporting 1.3G used on a 2G system, so its reporting pages that are used for disk caching as well as used, which it "technically" used but will be freed by the OS once we run low on RAM

Instead stat should just report (used - buffers cached) and (buffers cached in brackets)

Otherwise people using this information may be mislead as to how bad stuff really is ( http://www.linuxatemyram.com/ )

Also recommend using standard unix postfixes here, so it 1.311G not 1.311 GiB
