Wikipedia says: "When a process crashes, it neatly exits and sends a message to the controlling process which can then take action, such as starting a new process that takes over the old process's task" But this seems only a small piece of what would be needed. And if the idea is to have a main process spawning a tread (or process) for each "thing" it has to do so that the thread can be neatly re-spawed in case of failure, how is this much better done in Erlang than in any other programming language? Can you please elaborate?
