We depend on the
{ns, lastmod}index on config.chunks being used in the chunk diff query to config.chunks so that yielding does not cause us to miss chunk documents and never see them. We should include a hint on the query to assure that the query planner uses that index for the request: it's very unlikely that the planner will choose not to use that index, but the planner can technically choose to use something else.
