Why would we expect the same environment variables to exist for the whole program? On a loosely-connected cluster, each image is going to have its own set of environment variables and some could well be different (like HOST for example). We probably ought to say that environment variables are per-image. The current text certainly implies that GET_ENVIRONMENT_VARIABLE will return the same value on each image, and that is surely a limitation we don't want to apply.
