I am curious what motivated the choice of 'volatile'.

In my own case I will sometimes speculatively use 'volatile' to mark fields 
not essential to state despite that the class does not implement 
'Serializable'. While this violates the rigid rule prohibiting superfluity, I 
aver that the marker aids reasoning about the state in such cases.

This doesn't seem to be that.
