Cache: only complain on long locked entries. There have been multiple reports of cases where a real locked entry was removed, resulting in a segmentation fault later in a worker which locked the entry. It looks like default inactive timeout isn't enough in real life. For now just ignore such locked entries, and move them to the top of the inactive queue to allow processing of other entries.
