    Description

      The aggregation framework doesn't currently have a notion of which fields are referenced, but this will come with SERVER-4644. Once that is in place, the arguments to ClientCursor::yieldSometimes() should be improved to take advantage of index-only queries when possible. However, at this time, apparently the RecordNeeds variations aren't all implemented, and still require too much knowledge on the callers' part. See the related tickets above.
