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 

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.
