Image Decomposition

Looking at the swarm image we built previously, it's a couple of hundred MB in size -- for a small application. This image size will not slow down execution, since only files are touched which are needed when the application starts, but it will still be offending an aesthete's eye. Specifically for mainframers who have tried to save on every bit, because their core memory only had a couple of them (my knowledge is entirely anecdotal...). How can we kill that pain?
