There's not a huge difference between the domain of telecom switches and modern web applications. You've got multiple clients connecting, with the understanding that one client shouldn't have undue impact on the responsiveness seen by other clients. This is even more true once you get into using websockets which are directly analogous to active calls in a telecom switch - one websocket channel dying shouldn't cause other user's channels to be killed as well.
