 Review comment:
   It takes some time for the znode changes to propagate to the listener. Back 
when I had done the origin remote registry work, I had used much shorter delay 
intervals in the tests, but then the tests would intermittently fail. The delay 
in those tests was bumped to 1s, so I've done the same here, to avoid the same 
intermittent failures.
