uwsgi keystone under master process

Browse Source 
Normally a standalone uwsgi server would run in "master" mode -- it
handles signals to reload the processes. I tried this originally
with keystone but found that the server didn't shut down when
unstacking. The reason it didn't shut down is because (by default)
uwsgi does a reload on SIGTERM & SIGHUP rather than shutting down by
default, see [1].

Setting "die-on-term = true" & "exit-on-reload = true" changes the
uwsgi server to shut down when unstacking.
