We will talk about fences and I will show them how to do pointer manipulation in Java.. and how it can be used to implement wait-free, non-blocking algorithms.. I will show them how to get measurements to understand when their applications are fighting with the hardware... That said, I really wished that we had a better... safer way to achieve the same effect than exposing people to unsafe.

If you have a pointer to the talk itself, or related materials, I would love to see it.  How much do you know about the crazy world of GC implementation?  GC surprises are the root cause of most of the Unsafe-induced bugs I've seen.
