Hello
Sorry for the newbie question, but I was wondering: When launching
multiple uWSGI processes, do they all share a single Python
interpreter in RAM?
Here's what "uwsgi --http-socket :9090 --plugin=python --wsgi-file
hello.py-processes 4 --threads 2" says;
================================

And here's what "ps aux" says:

================================
Thank you.
