This was actually right. From the documentation
    
    > By default sending the SIGTERM signal to uWSGI means "brutally
    > reload the stack" while the convention is to shut an application
    > down on SIGTERM. To shutdown uWSGI use SIGINT or SIGQUIT instead.
    > If you absolutely can not live with uWSGI being so disrespectful
    > towards SIGTERM, by all means enable the die-on-term option.

    And:
    
    > Sending SIGHUP to the Emperor will reload all vassals.
