That is if the JobQueue is still open. If the queue is closed, this will just silently do nothing. To get data back out of this process, give ``process`` access to a ``multiprocessing.Queue`` object, and give it here as ``queue``. Then ``JobQueue.run`` will include the queue's contents in its return value. isjob queue appended %s.N(RRtappendR Rtname(Rtprocess((s^/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/fabric/job_queue.pyRLs  c€s‡fd†}i}x'ˆjD]}tjd ƒ||js  µ $
