    from twisted.web import client
    from twisted.internet import defer, reactor

    TIMEOUT = 30.0
    URL_LIST = ['http://www.mojam.com/']

    dList = [client.getPage(u) for u in URL_LIST]
    for d in dList:
        d.setTimeout(TIMEOUT)

    d = defer.DeferredList(dList)
    pages = []
    d.addCallback(pages.extend).addCallback(lambda R: reactor.stop())

    reactor.run()
    print pages   # Or whatever
