Actually I had dinner with Graham Dumpleton (mod_wsgi author) recently when he was in the San Francisco and he was speculating about the benefits of having nginx handle all the requests and proxy the django requests to Apache. In this case instead of a memory expensive thread/process under Apache being open while input and output streams to the server, a relatively less expensive nginx thread handles the request or response, basically buffering it and passing it on to the server or client only when data transfer is complete.
