native_state troubles

[John Keiser]

        Jeez, multiple VMs are a friggin *nightmare* -- this whole class caching
issue is just one facet.
        native_state will have the same problems.  Thankfully, it shouldn't be too
hard to modify for multiple VMs, because of Paul's good design.  Instead of
a static state_table, some sort of per-VM cache of state_tables would be
better.
