Instead use external pointer block lists so that the same weakling can be pending for both minor and major GC at the same time. When we begin marking through new-space in major GCs, this will need to happen for weaklings in new-space. Once the pending lists are independent, it is easy to handle the reverse case. This also improves the promptness with which old-space weaklings with unreachable new-space targets are clear.
