It's not clear (to me) that these should be volatile. I also wonder 
about setting the initial value too as volatile could make this 
expensive in some environments.

Are you sure there isn't any serialization impact? Zeros has also meant 
these are uninitialized so I just wonder about deserializing on an older 
JDK.
