I don't think a pass proves anything in that respect. I've seen so many 
tests being flaky because they assume things that aren't always true 
(like being the only thing running, or having race conditions that get 
exposed on certain hardware or setups).

Regarding "overload"; in my opinion a database server like MariaDB 
should be resilient against a heavily loaded server. No data corruption 
should occur under load. I'm wondering what it means if a loaded system 
could cause your tests to fail. Could it be that the *test* is sensitive 
to a loaded system (e.g. race conditions) and that a failure isn't 
representing the actual MariaDB server?
