Wow, wonderful post that I hadn't read yet. In particular the 'fuse' type stuff is really important when you have a real world system where "let it crash!" is not really ok, because you have, say, a user interface, or a web server that should not be part of everything just crashing. In particular, something I've seen: if your Erlang application talks to a database, and the database goes down for some reason, it may be desirable to have the whole application not go down with it! Thank you!
