It provides "zero" overhead tracing by actually re-writing the in-memory process images with instrumented instructions. In FreeBSD, it can be used to count individual system calls down to the level that would typically require a debugger (without the debugger overhead). I know I mentioned DTrace a while back on this list, but didn't have much information to provide. Ping me if you want to know more. I'm not an expert, but have used it a little to trace system calls on a BBB in FreeBSD. As I have said before, DTrace may be way outside a GSOC project, but want to make sure it gets mentioned in the context of this discussion.
