   > I am curious why artifact staging does not work with threads? I wonder if we should fix that instead of introducing yet more complexity to this already complex API.
   > 
   > In Python, I thought we used processes instead of threads because of the GIL. But Java has no GIL, so I'm not sure there is an advantage to using processes.
   
   Using threads still makes sense for IO bound tasks in Python since Python can parallelize IO effectively. Python's GIL is problematic for CPU bound tasks.
