      http://buildbot.askmonty.org/buildbot/builders/kvm-bintar-centos5-x86/builds/1892/steps/test/logs/stdio

      main.plugin_loaderr                      w2 [ fail ]  timeout after 900 seconds
              Test ended at 2014-11-23 09:21:08
       
      Test case timeout after 900 seconds
       
      ...

      The problem is reproducible on CentOS 5.9 32-bit, but I am not getting it on Wheezy 32 bit.

      What happens there is that the test shuts down the server, then attempts to start it with a wrong set of options, the attempt is expected to fail and abort, and then the server is restarted properly to finish the test.
      On CentOS 5 32-bit the "bad" attempt indeed fails, too, but the server hangs upon shutdown.
      It can be well enough reproducible by just running the command line

      /home/elenst/mariadb-10.1.2-linux-i686/bin/mysqld --basedir=/home/elenst/mariadb-10.1.2-linux-i686 --innodb_read_io_threads=2 --innodb=force --innodb-page-size=6000

      The hang does not happen every time, but was happening often enough for me when I was trying it (~9 times out of 10).

      Stack trace from the hanging server:
