Even then a scene might not benefit much, as a second
blurred refraction object would need to be positioned
such that it appears in the first blurred refraction
for this technique to help. Refraction tends to be
less annoyingly recursive than reflection ;)

BTW I just tried: if the refraction leads to total
internal reflection the no_reflection modifier will
take effect.
