Description

If user launches two tasks with the same Docker image simultaneously (e.g., run mesos-executor twice with the same Docker image), there will be a staging directory which is for the second task never cleaned up, like this:

└── store
    └── docker
        ├── layers
        │    ...
        ├── staging
        │   └── a6rXWC
        └── storedImages
