It seems this failure doesn't happen all the time for me. Running it a few
times, I see also see the FileNotFoundError, but in 1 out of 2 cases,
approximately.
Now, when running it on an actual example in the interactive terminal (from
a small dataset where I actually deleted one of the files), I consistently see
the segfault:
```
In [1]: import pyarrow.dataset as ds
In [2]: dataset = ds.parquet_dataset("/tmp/tmp9qt6cph5/_metadata")
In [3]: dataset.to_table()
terminate called after throwing an instance of 'std::system_error'
what(): Invalid argument
Aborted (core dumped)
```
I get a different stacktrace when running the tests, something about the
"unlink", so it might be that the way I remove the file in the test is not very
robust / is not similar to deleting a file in the file browser.
