      Description

      galera_sr.mysql-wsrep-features#165 test test fails sporadically in Codership jenkins testing.
      The failure is due to debug sync point wait timeout. The test itself has two sequential SQL statements being asynchronously sent for execution (--send), without later checking the progress of the execution, and this is likely the cause for the failures, The failing test case output looks like the following:
