Understood.  One thing tho.  Do you think having ATTACH_NO_STOP would
be better?  I think that's a noticeable difference.  To me, it seems
to only complicate things.  If we decide to go for
ATTACH_STOP_WITHOUT_SIDE_EFFECT then the difference between that and
INTERRUPT again becomes really small, so that was the reason why I
proposed to have a unified one.

Thanks.
