I mean that the library will not attempt to catch any exceptions thrown from
actions. Since the state machine could likely be in an unstable state when
such an exception is thrown, it must be terminated before the exception is
propagated to the client (I'm not doing this with try { ... } catch ( ... )
{ terminate(); }but with a scope guard).
