      OplogInterfaceLocal::next() returns an unowned BSONObj. This is problematic because callers in RollBackLocalOperations::onRemoteOperation() save the resulting object and call next() several times without taking ownership first. This results in a bugs where an unowned BSONObj can point to freed or overwritten memory.
