I have no idea why I would ever want to use tracepoints. As far as I can see, anything I can do with a tracepoint I can do by logging data in my program--and if I add the logging code to the program, the code is ready and waiting for the next time I have a problem. There is probably some cool use for which tracepoints are the obvious right answer, but I don't know what it is. Ian
