Sort-of like VW's perm space (which is not garbage-collected ever) which would be the "base-image", plus all the rest in a second image file. This would allow to share a base image and a differential image in a similar fashion as we have a sources and a changes file. A regular save would just save the non-permanent part of the object memory.
The other thing this would buy us is the ability to do FLASH-memory
based devices. Those objects (and of course that includes code) that
are "permanent" can be in PermSpace, which physically sits in FLASH.
