But also without that, it gets called after every 30th test returning -- since usually the fast tests run quickly in parallel, we would call it more frequently at the beginning of the tests. Note that the "check_kmemleak_force" function in the run-tests.sh script does NOT run in parallel. I am not familiar with kmemleak, but seems not serious. Maybe just ignore the error output?
