As the web component is basically a thin admin interface for a background
service and the web part will have zero load / reliability concerns, I am
not too worried about using the built-in flask server, but it would be nice
regardless to get uwsgi working. I put the uwsgi.ini in the project home in
accordance with the instructions here
<https://wikitech.wikimedia.org/w/index.php?title=Help:Tool_Labs/Web&oldid=796257#Python_.28uwsgi-plain.29>,
does it actually belong in ~/www/python as you said?
