Gevent Pywsgi Server - Multiprocessing?

Question

Il seguente codice (preso da qui: https://bitbucket.org/denis/gevent/src/6c710e8ae58b/examples/wsgiserver_sssl.py) implementa un server WSGI estremamente veloce alimentato in serra:

#!/usr/bin/python
"""Secure WSGI server example based on gevent.pywsgi"""

from gevent import pywsgi


def hello_world(env, start_response):
    if env['PATH_INFO'] == '/':
        start_response('200 OK', [('Content-Type', 'text/html')])
        return ["<b>hello world</b>"]
    else:
        start_response('404 Not Found', [('Content-Type', 'text/html')])
        return ['<h1>Not Found</h1>']

print 'Serving on https://127.0.0.1:8443'
server = pywsgi.WSGIServer(('0.0.0.0', 8443), hello_world, keyfile='server.key', certfile='server.crt')
# to start the server asynchronously, call server.start()
# we use blocking serve_forever() here because we have no other jobs
server.serve_forever()

Tuttavia, questo funziona solo su un nucleo. Come modificheresti questo per sfruttare più processi? Non cercare una risposta che coinvolge Gunicorn, alla ricerca di qualcosa di più semplice.

SUGGERIMENTO

Ecco un campione di codice che utilizza Gevent e multiprocessing, ma non riesco ancora a capire come far funzionare questo con WSGI (prelevato da https://gist.github.com/1169975):

import sys
from gevent import server
from gevent.baseserver import _tcp_listener
from gevent.monkey import patch_all; patch_all()
from multiprocessing import Process, current_process, cpu_count


def note(format, *args):
    sys.stderr.write('[%s]\t%s\n' % (current_process().name, format%args))

def echo(socket, address):
    print 'New connection from %s:%s' % address
    fileobj = socket.makefile()
    fileobj.write('Welcome to the echo server! Type quit to exit.\r\n')
    fileobj.write('In %s\r\n' % current_process().name)
    fileobj.flush()
    while True:
        line = fileobj.readline()
        if not line:
            print "client disconnected"
            break
        if line.strip().lower() == 'quit':
            print "client quit"
            break
        fileobj.write(current_process().name + '\t' + line)
        fileobj.flush()
        print "echoed", repr(line)

listener = _tcp_listener(('127.0.0.1', 8001))

def serve_forever(listener):
    note('starting server')
    server.StreamServer(listener, echo).serve_forever()

number_of_processes = 5
print 'Starting %s processes' % number_of_processes
for i in range(number_of_processes):
    Process(target=serve_forever, args=(listener,)).start()

serve_forever(listener)
