Run? Rarely. But it does happen.
We're finding it tougher to judge in 4E because of the debilitating area attacks that some monsters have. We have a tendency to not want to cluster for area attacks, but that's competing with the desire to maintain a choke point to allow escape should things turn sour.
Usually the catalyst to flee is when someone suffers bloodied value damage in one attack or 2 or more characters are down. Otherwise it's unload daily powers and action points and crack on!
