```
pip install scalene
```
Then I created a file called `run_tests.py` with the following contents:
```python
if __name__ == ""__main__"":
import sys, pytest
pytest.main(sys.argv)
```
Then I ran this:
```
scalene --profile-all run_tests.py -sv -x .
```
But... it quit with a segmentation fault!
```
(datasette) datasette % scalene --profile-all run_tests.py -sv -x .
