+Run the ctdb_bench test and sanity check the output.
+
+This doesn't test for performance regressions or similarly anything
+useful.  Only vague sanity checking of results is done.
+
+Prerequisites:
+
+* An active CTDB cluster with at least 2 active nodes.
+
+Steps:
+
+1. Verify that the status on all of the ctdb nodes is 'OK'.
+2. Run ctdb_bench on all nodes with default options.
+3. Ensure that the number of +ve and -ive messages are within 1% of
+   each other.
+4. Ensure that the number of messages per second is greater than 10.
+
+Expected results:
+
+* ctdb_bench runs without error and prints reasonable results.
