PEP 333 allows the WSGI gateway to buffer the input if it chooses to do
so: "The server or gateway may perform reads on-demand as requested by
the application, or it may pre- read the client's request body and
buffer it in-memory or on disk, or use any other technique for providing
such an input stream, according to its preference."
