We > need something more akin to trace-redisplay. I must say upfront that I've only read about dtrace for a couple hours and asked Gemini a few questions. From that, my understanding is that an application can generate its own application-specific events that carry additional data, including strings, int, floats, and so on, structs (not sure if I believe Gemini in that case, but who knows). (Helmut, please correct me if that's wrong.) If that's true, one could include the info needed for a redisplay trace in the event. What events to generate for what is of course another question.
