   I think this issue is a duplicate of #32372. I've added more details in that issue, but in a nutshell, pyarrow.fs.copy_files hangs for s3 buckets and with `use_threads=True` if more files are uploaded than CPU cores available:
   
   ```
   mkdir -p /tmp/pa-s3
   cd /tmp/pa-s3 
   for i in {1..7}; do touch $i.txt; done
   # This works
   python -c "import pyarrow.fs; pyarrow.fs.copy_files('/tmp/pa-s3', 's3://bucket/folder')"
   for i in {1..8}; do touch $i.txt; done  
   # This hangs forever
   python -c "import pyarrow.fs; pyarrow.fs.copy_files('/tmp/pa-s3', 's3://bucket/folder')"
   ```
