Notes
- 1.
This is not quite true: twisted.web, an asynchronous webserver, is somehow able to run synchronous blocking WSGI applications. It does this by invoking the WSGI application in a background thread and using a Deferred to communicate the result of that invocation back to the server. This does work, but it still means that the core of the business logic is being dispatched to a synchronous pool of background threads: not ideal from the perspective of scaling!
