---------------------------------------
This time the test timed out. And I see this:

So looks like I traded a race for stopping/starting the HBase mini cluster with
a race further down the stack.
The test in trunk actually starts dfs/zk only once. I port that part back as
well, that would avoid this race and also speed up the test.
Addendum coming soon.
