Dtrace OSCON session

I'm in a session on Dtrace, being given by Bryan Cantrill, who is one of the Dtrace authors.  I have to say that Dtrace is really nice.  Someone needs to implement this for Linux - it's really useful.  DProbes was the closest thing I could find for Linux, and it's not even in the same ballpark.  This tool really has the ability to save you tons of time when debugging system performance problems.
