That looks to be a nice idea. We should certainly look into this possibility. However can we look at this option probably a little later? Our plan was to do one step at a time i.e have the basic uprobes in first and target the booster (i.e jump to the next instruction without the need for single-stepping next). We could look at this option of using jump instead of int3 after we are done with the booster. Hope that's okay. -- Thanks and Regards Srikar
