Leopard features

I was lucky enough to get a ticket to attend WWDC this year, and I've been looking over the session schedule to see what the sessions are, when I ran across this interesting little blurb: > DTrace, an open source project which provides insight into the > interaction between your code and the OS kernel, is now available as > part of Leopard. This session will explain how kernel developers can > both take advantage of, and extend, DTrace's functionality to help > debug and optimize low-level code.

DTrace in MacOS X? Hell yes!
