I think this mechanism should handle applications that have breakpoints builtin as well because i am thinking they are going to use ptrace interface as well to register the breakpoint, is that correct.
No, such applications (at least, mine) are going to insert int3 by hand
in the code (yes, I know, this is evil but it is possible).
If you are interested, it is some sort of profiler/tracer available from there: http://www-sop.inria.fr/dream/personnel/Mathieu.Lacage/bozo- profiler/
