I'd hate to see the Plan 9 ideas turned into subjecting some unfortunate programmer(s) with having to write hundreds of thousands of probes instead of following the more acid based approach. dtrace has it's place. And as you've said, eye candy wins. But I still think there's a way to use acid and the linker to provide the kinds of hooks you want for debugging. -jas On Oct 27, 2009, at 9:23 PM, ron minnich wrote: > One other thought on this line.
