-* sim: updateSimRepoState turns out to call preferredContentSet repeatedly

-  Note that this test case does not behave this way if the final

 * sim: Can a cluster using size balanced preferred content be simulated?
   May need the sim to get the concept of a cluster gateway, since the
   gateway is what picks amoung the nodes on the basis of size. On the other
