uwsgi Master Process

If you are just getting your feet wet with uWSGI, you might have run into the following error when running it.

*** WARNING: you are running uWSGI without its master process manager ***

To run uWSGI with the master process add the flag -M flag when running uWSGI. Then you will get the following nice message.

spawned uWSGI master process (pid: 755)

The Master process manager will respawn your process if or when it dies. See this reference doc about the flag.
