Multiprocessing does not work on Goose().extract(raw_html=...)

[codelucas]

This was tested with python's multiprocessing library.

I checked the code, everything hangs at the line prior to Goose().extract(...)
not at join() or run(), etc.

This example is specific but the problem is general. Has anyone gotten multiprocessing to work with
goose's extraction period? If so a brief explanation of how or a tiny code snippet sample would be great thanks.

Or at least an explanation of why my code blow is incorrect would be great.!

Sorry if i'm doing something blatantly wrong. This is my first time
doing multiprocessing in python.

from multiprocessing import Process, Queue
from multiprocessing import cpu_count as num_cores
import pickle
import codecs
from goose import Goose

class Processor(Process):

    def __init__(self, queue, html):
        super(Processor, self).__init__()
        self.queue = queue
        self.html = html

    def ret(self):
        g = Goose()
        article = g.extract(raw_html=self.html)  # THE CODE HANGS HERE
        pickle.dump(article, codecs.open(str(id(article))+'.txt', 'wb'))
        return str(id(article))

    def run(self):
        self.queue.put(self.ret())

processes = []

if __name__ == '__main__':
     for i in range(0, num_cores()):
         q = Queue()
         html = ... 
         p = Processor(q, html)
         processes.append((p, q))
         print 'appending', (p, q)
         p.start()

     for val in processes:
         val[0].join()
         id_ = val[1].get()
         article = pickle.load( codecs.open(id_+'.txt', 'rb'))
         print article.cleaned_text
