man_update.py: ProcessPoolExecutor dead-locks after refactoring
Created by: lahwaacz
update.py to a Django management command
man_update.py, the original code using
concurrent.futures.ProcessPoolExecutor leads to a dead-lock. Django's
manage.py probably uses more stuff which cannot be pickled and copied into subprocesses...
concurrent.futures.ThreadPoolExecutor as a workaround, but with a lower performance.
