Here is an example using spynner:

import spynner
from multiprocessing import Process, Queue


class MarketingSensoriale(BasicNewsRecipe):

    title                 = u'Marketing sensoriale'
    description           = 'Marketing Sensoriale, il Blog'
    category              = 'Blog'
    oldest_article        = 7
    max_articles_per_feed = 200
    no_stylesheets        = True
    encoding              = 'utf8'
    use_embedded_content  = False
    language              = 'it'
    remove_empty_feeds    = True
    recursions = 0
    auto_cleanup = False

    remove_tags_after    = [dict(name='div', attrs={'class':['article-footer']})]
    

    def get_article_url(self, article):
        return article.get('feedburner_origlink',  None)


    def grab(self,q,url):
        try:
            browser = spynner.Browser()
            browser.load(url)
            #10 second timeout
            browser.wait_load(10)
            q.put(browser.html) 
            browser.close()
        except:
            q.put(None)  

    def preprocess_raw_html(self, raw, url):
        q = Queue()        
        p = Process(target=self.grab, args=(q,url))
        p.start()
        html = q.get()
        return html


    feeds          = [(u'Marketing sensoriale', u'http://feeds.feedburner.com/MarketingSensoriale?format=xml')]

You need to install spynner before this will work.
