The base class carried a lazy_views flag, a _views_source field, a _build_views split and an introspection check for subclasses that decorate their views - all of it shared by 37 plugins to serve one. Overriding update_views/get_views in processlist does the same with no change to model.py, and set_views/reset_views clear the pending flag so a reset stays reset.
