This is already impossible to do *portably* with WSGI, because PEP 333
already allows the gateway to cache the request body at its own
discretion. The last time I checked, Lighttpd and nginx both cached the
entire request body before handing it off to back end [Fast|S]CGI
processes. Most web accelerator proxies work the same way.

I do agree that it should not be *required* behavior, but it should be
*allowed* behavior.
