This one causes a regression for me in a test case that first kills one
zone and then a littler later a second one and then checks that all
blocks have the expected replication level.

The specific test cases uses 4 initial zones and a replication level of two,
but I suspect other combinaions would work too.

Figuring out what is going on exactly now.
