Just a quick update on this for anyone still interested. To the list of exceptions to explicitly ignore in your uncaught exception handler, include NSPortTimeoutExceptions. These happen (rarely) when the spell checking service is busy or slow to start up (I'm not sure which, it's happening on a customer's machine). There are also probably other cases, although we haven't seen any. Other than that, and a one-off crash on Tiger that actually looks like a Tiger bug, the scheme is working well, in the sense that one learns interesting things without inconveniencing users unduly.
