This test uses SHOW STATUS and the like, which may be unstable in the face of logging to table, since the CSV handler is actively executing operations and thus incrementing the counters. Fixed by disabling logging to table for the duration of the test and restoring it afterwards. This causes various counters to properly start counting from zero and never advance due to CSV operations.
