   > I'm taking a look at this. I have one debugging question for you in the meantime however. When I look at _upload_to_uri_with_exclude it appears that it is a recursive copy. Is there a possibility that you've included the current directory "." or parent directory ".." and that's why the operation never finishes? 
   
   In our case, `exclude` is None, so that code path to `_upload_to_uri_with_exclude` is actually never hit (and you'll notice it doesn't show in the flamegraph). So, it's essentially just the call to `pyarrow.fs.copy_files`.
