This is really just a workaround to keep SystemMonitor's process table working right wrt selection retention during resorts (while also doing full index invalidation on things like ProfileViewer inversion.) It's starting to feel like the model abstraction is not super great and we'll need a better approach if we want to actually build some more dynamic functionality into our views.
