At the machine level, the DEC Alpha used to be the platform that would

You can see in the cookbook that the Alpha has little respect for data
dependencies and consequentially needs a lot of memory barriers:
On the other hand, since Alpha's Java VM implementation is so tightly
fenced, perhaps the Java apps running on it are *less* likely to do anything
