Docker commands hang after exiting attached container

Expected behavior

The commands should load.

Actual behavior

Any command just hangs on executing (docker ps, docker info, etc.)

  - a reproducible case if this is a bug, Dockerfiles FTW

  - host distribution and version ( OSX 10.10.x, OSX 10.11.x, Windows, etc )
**OS X 10.12**

### Steps to reproduce the behavior

1. Run a container attached (`docker start -a ghost`)
2. Try to exit the attached terminal (`ctrl-c`) but nothing seems to work, so I just exit the terminal windows.
3. Open a new window, type any command (`docker ps`) and it just hangs there for eternity.
4. Try to restart Docker, and it just hangs on "starting..."
