I was careless and I'm sure you're right. What I *should* have said is, "lots of Linux devs
would spend a lot of their time incorporating DTrace, if only the licenses allowed it."
But my point remains: you seem to be interpreting license problems as a lack of desire. The
desire is there, no question! If the licensing problems could just be fixed somehow, I'm
confident the Linux camp would devote amazing hours to DTrace.
As it is, they have to devote amazing hours to replicating DTrace. :(
