      To ensure operations are idempotent, $push does things like:

      "o2" : { "_id" : ObjectId("4fa9426c9c7d54fb76105a20"), "someArray" : { "$size" : 1 }
// or
"o2" : { "_id" : ObjectId("4fa9426c9c7d54fb76105a20"), "someArray" : null }

      But the replication code ignores the second field:

      BSONObjBuilder b;
b.append(_id); // criteria is only _id field!
updateObjects(ns, o, b.done(), true, false, false , debug, false,
    QueryPlanSelectionPolicy::idElseNatural() );
