Comment (by naokikambe):

 Taking so long time was due to my wrong fix. But if I reverted the last
 change, tests for "b10-stats-httpd" need open files more than 256. In that
 test, many open files are used. Because http server and http client
 objects are created many times and some other IO objects are used at same
 time. So the number of mock auth instances was reduced. Could you try
 again? And please refer to the following log for the detail?:
