This is realistic for the situation of one point light. When light is
refracted, *all* of it is refracted, none of it gets past without having
it's path bent. This means the edges of the shadow, where the light is
being refracted away, will be black.
You usually don't see this in real life, because diffusely reflected
light illuminates the shadow(both directly and indirectly, through the
refracting object), and you usually have more than one light source. You
should get more realistic effects by using more lights and radiosity.
