Thanks for the discussion on external loops for memory management.

For my use case of running the Python script fresh every minute on a VPS, I'm leaning towards using a cron job.

It seems more robust for a persistent "every minute" task on a server compared to a manual Bash while loop because:

cron handles server reboots and session disconnections automatically.

It's the standard Linux tool for scheduled tasks.

It's efficient for this kind of periodic execution.

My Python script would then just perform one "global cycle" and exit, with cron handling the "every minute" relaunch. For example:

* * * * * /usr/bin/python3 /path/to/my_script.py >> /path/to/log.txt 2>&1

This ensures a complete memory reset for each run. Am I on the right track for this specific VPS "every minute" scenario, or are there strong reasons to prefer a continuously running Bash loop with nohup/tmux?
