ValueError: buffer source array is read-only

### Describe the bug

Hi,

When training RandomForestClassifier using multiple cores (n_jobs=-1) I get the following error (full traceback below):

    ValueError: buffer source array is read-only

This doesn't happen when using just one core or when a small dataset is used for training (by subsampling a large one).

It's not straightforward to provide reproducible code as this happens with a fairly large dataset (~100K training records).

The code is running on a MacBook Pro (6-Core Intel Core i7, Monterey 12.5.1) under Python 3.9 (see version info below).

Note: A similar error is mentioned in bug reports #15851 and #16331 - but it appears this issue has not been fully fixed.

Thanks,
Ron


### Steps/Code to Reproduce

Here are the relevant lines of code:

```python
    clf = Pipeline([
        ('tfidf', TfidfVectorizer(ngram_range=(1, 1),
                                  use_idf=True,
                                  max_df=1.0,
                                  max_features=None
                                  )
         ),
        ('chi2p', SelectPercentile(chi2, percentile=100)),
        ('clf', CalibratedClassifierCV(RandomForestClassifier(random_state=None,
                                                              max_depth=50,
                                                              class_weight='balanced',
                                                              n_jobs=-1
                                                              )
                                       )
         )
    ])

    clf.fit(data_train, target_train)
```

### Expected Results

No error is thrown.

COMMENT:
The large datasets will trigger `Parallel` to `memmap` them in read-only mode. Looking at the previous issue, we should check with which `dtype` the memmaping happened to see if we can force it and reproduce it with a simple input array.
