I found a pragmatic solution. After I make my calls that will trigger
gui changes, I use  Thread.yield(); in my computational thread to give
the Swing thread a crack at processing the GUI events.

I still get sporadic anomalies.

It's normal situation if a table model is updated by a non-Swing
thread.
IMHO, If you've extends an AbstractTableModel class, you can override
the fireTableChanged method:

<pre>
public class Model extends DefaultTableModel {
    private static final long serialVersionUID =
-5792073620222974655L;
    @Override
    public void fireTableChanged(final TableModelEvent e) {
        if (SwingUtilities.isEventDispatchThread()) {
            super.fireTableChanged(e);
        } else {
            SwingUtilities.invokeLater(new Runnable() {
                @Override
                public void run() {
                    fireTableChanged(e);
                }
            });
        }
    }
}
</pre>
