It's mostly just 'ported' from regular Java, where a process could not do a normal 'exit' when non-daemon thread were still running. But you're right. It would seem that if android decides to 'kill' your app, it doesn't much matter whether there are some daemon threads still running or not. Still, be on the safe side, don't create these non-daemon thread :-)
