> run-test-hdfs was run repeatedly (n = 16) and the execution time of each test
> was recorded. Testfsck was by far the longest test, with a median run time
> of 564 seconds, nearly 10 minutes. This is a quarter of the entire time
> spent over the average 40 minute run for all the tests, and much too long for
> any individual test.
