Anything You Can Do, D Can Do Better!

Not sour grapes honest! Jon Haslam saw my fsflush post and couldn't just bask in the glory that was old school hacking. He had to throw the new hotness at the problem. I, for one, welcome our new DTrace overlords!

Speaking of DTrace, your last post on instruction tracing could probably be helped with DTrace's pid provider which lets you trace any instruction in any user-land application. I'd be very interested to hear about the relative costs of the techniques that DTrace uses compared with the utrap handler. There currently isn't a simple way to just instrument CTIs, but it would be a snap.
