Investigate uWSGI emperor.

While this likely is not a long term strategy, it may be useful to investigate regardless:

    If you need to deploy a big number of apps on a single server, or a group of 
    servers, the Emperor mode is just the ticket. It is a special uWSGI instance that 
    will monitor specific events and will spawn/stop/reload instances (known as 
    vassals, when managed by an Emperor) on demand.

Yeah, which is the kind of stuff I'm expecting to break in the QA deploy & then fix there.
