    Factor-out the `OverlapMode` from `OverlapFlag`.
    
    This seems a bit cleaner conceptually because the overlap mode and running
    in safety mode are quite orthogonal.
    
    More pragmatically, it also makes it possible to use `OverlapMode` to let
    programmers pick the overlap mode for individual instances.
