How to make uwsgi shut down if application failed to load?

I run my uwsgi in the simplest way possible, as a process managed by upstart, no emperor mode or anything. This is what I get if application fails on startup for some reason: ``` [traceback skipped] unable to load app 0 (mountpoint='') (callable not found or import error) *** no app loaded. going in full dynamic mode *** *** uWSGI is running in multiple interpreter mode *** spawned uWSGI master process (pid: 17923) spawned uWSGI worker 1 (pid: 17948, cores: 1) ... ``` I have no use for this mode, and would like it to shut down completely, so my upstart job shows as stopped. How can I do this?
