I have an idea why pitest fails on circleci. it seems that circleci reports that it has 32 cpu cores. so pitest will run with way too many threads. we could override the threads in an enviroment variable when we run in circleci. thats also an explanation why it worked when I tried running it locally with the circleci local command
