It is an interesting idea, but I think still too tied to debugedit. If at all possible we should take debugedit out of the loop completely. It just runs way too late in the build process. I see another thread where Andy has a good idea, that I think is more promising. Add an option to the linker, which will run at precisely the right time. I'll reply to that one with my thoughts.
