// These errors are returned by various specific workers in the hope that they
// will have some specific effect on the top-level agent running that worker.
//
// It should be clear that they don't belong here, and certainly shouldn't be
// used as they are today: e.g. a uniter has *no fricking idea* whether its
// host agent should shut down. A uniter can return ErrUnitDead, and its host
// might need to respond to that, perhaps by returning an error specific to
// *its* host; depending on these values punching right through N layers (but
// only when we want them to!) is kinda terrible.
