According to the documentation here: http://celery.readthedocs.org/en/latest/userguide/workers.html#process-signals

I should be able to send a SIGTERM to my running worker process and have it finish the task it is currently working on before it shuts down. However when I call sigterm the process exits immediately with the following traceback.

Traceback (most recent call last):
  File "/edx/app/edxapp/venvs/edxapp/local/lib/python2.7/site-packages/billiard/pool.py", line 1171, in mark_as_worker_lost
    human_status(exitcode)),
WorkerLostError: Worker exited prematurely: signal 15 (SIGTERM).

I'm using Celery 3.1.18 with django 1.4, is there something special that has to be done to integrate the signal handlers with django?
