Leaking semaphore

```
/Users/elias/.pyenv/versions/3.11.2/lib/python3.11/multiprocessing/resource_tracker.py:224: UserWarning: resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown
```

Every time my script shuts down i get a warning about a leaked semaphore. I am guessing we are forgetting to free some python memory somewhere somehow.
