but why do we need two approaches to be at all explicit?   Basically, if you write a WSGI application, you normally are writing non-threaded code with a shared nothing approach.  Whether the WSGI app is used in a threaded apache container or a gevent style uWSGI container is a deployment option.  This shouldn’t be exposed in the code.
