I rarely found conflicts in trace-events, but in this case you would indeed have them. Trivial to solve, however. > In parallel to the completely disastrous user experience when using trace > points. What exactly is disastrous? We could have improvements (such as having multiple trace backends compiled in an executable, e.g. simple+stderr, or having gdb magic to enable/disable them from command breakpoints). But in general, I find trace points to be quite easy to use, and unintrusive enough to let you debug performance problems. Paolo
