FWIW the IBM VME available for Harmony doesn't do a good job of 
distributing the identityHashCode.

We had this discussion a awhile ago, and since we don't know what the 
distribution of the VM hashCode implementation will be, the only thing 
to do is assume that the VM is producing a good distribution, and let 
them suffer the consequences if they do not.
