That's pretty cool; nicely done.
I'd quibble about a couple of minor things:
In Data Race Example: Using Barriers, the use of a naked StoreStore is
rather terrifying. In real-world code it'd be better to use
StoreStore|LoadStore or release unless the author really knows what
The use of "fence" to mean a full barrier is rather idiosyncratic; it
confused me the first time I saw it in HotSpot source, and from time
to time it still does.
But, as I said, these are minor criticisms.
