Tries to read the next request. When the header of the request is successfully
read, the method returns the request object (see above). It is connected
with the socket and can read the request body.
<p>
After receiving the request, one must either call <code class="code">accept_body</code> when the
request is acceptable and one want to reply afer evaluating the body, or
invoke <code class="code">reject_body</code> when the request can be denied without looking at the
body. One must also call <code class="code">accept_body</code> when there is not any body (it
is a no-op then). The HTTP protocol explicitly forbids to perform the request
when <code class="code">reject_body</code> has been invoked ("<code class="code">The origin server</code> MUST NOT
perform the requested method if it returns a final status code").
<p>
The response must be written to the Netcgi environment. Depending on
<code class="code">config_reactor_synch</code> the response is immediately transmitted to the
client or at some specified time in the future (untransmitted data is buffered
in this case).
<p>
While transmitting output, the reactor is able to read the next request
in the background when the limits for the pipeline size allows that.
<p>
While receiving input, the reactor is able to write untransmitted response
data in the background.
<p>
It is <b>an error</b> to call <code class="code">next_request</code> again before the previous request
is completely processed (you can ensure this by calling <code class="code">finish</code>).
In this case the HTTP connection is immediately shut down.
<p>
The method <code class="code">next_request</code> returns <code class="code">None</code> when all requests of the
connection are processed.<br>

Closes the file descriptor with a reliable method. This method must be

and may cost some time).<br>
