PERF: models with multithreading being slower than the same model with a single thread

While working on `skops`'s persistence, I realized sometimes it's faster for me to set `OMP_NUM_THREADS=1`.

I tried to isolate the issue. The differences here aren't large, and couldn't reproduce a massive difference, but in terms of proportions, the diffs are sometimes significant.

Here's the code to run the relevant tests, w/o any `skops` dependency:

The two compared runs are:

```bash
OMP_NUM_THREADS=1 /bin/time pytest -vv -s -x /tmp/test_persist.py
```

and 

```bash
/bin/time pytest -vv -s -x /tmp/test_persist.py
```

And merging the outputs of the files, calculating the time diff and sorting them, on my system I get:

__EDIT__: report and sort based on `multi / single` times.

COMMENT:
For debugging, can you check what happens when `OMP_NUM_THREADS=2` and `OMP_NUM_THREADS=6` for `HistGradientBoostingClassifier`? With the i7-9750H, I assume 6 is the default, but I think it's good to make sure.
