          Description

          For example:

          https://buildbot.askmonty.org/buildbot/builders/kvm-deb-wheezy-x86/builds/1532

          perfschema.setup_instruments_defaults    w1 [ fail ]
        Test ended at 2014-12-12 23:58:11

CURRENT_TEST: perfschema.setup_instruments_defaults
mysqltest: At line 82: query 'SELECT * FROM performance_schema.setup_instruments
WHERE name like "%wait/io/table/sql/handler%"' failed: 2006: MySQL server has gone away

          The testcase does a server restart during the test. I believe the problem is
          that it does not correctly synchronise with that server restart. It tries to
          reconnect after the server has restarted. But without proper synchronisation,
          the reconnect can succeed before the server has completely stopped. Then the
          following queries fail as the stopping server disconnects the connection that
          reconnected too early.
