Overall this looks very straightforward, almost suspiciously straightforward :-)

Can you verbally explain what the state is after this commit? We essentially do symbol resolution separately within the both namespaces - and when writing the final image, we just serialize all included Chunks into the output image?

What's the reason why we now link two separate copies of the load config in the testcases - what difference does that make? (If we wouldn't be linking two load configs but run the old testcases as they were, what would the results be?)
