ValueError: signal only works in main thread

See original GitHub issue

Hi, I used in Django runserver (dev) and uwsgi (production), same exception raised. It’s due to signal cannot be used in non-main thread.

Currently I have to monkey-patch HAS_SIGNAL = True to HAS_SIGNAL = False in f5/bigip/__init__.py. Hope there will be an option to disable signal use. Thanks.

File "/usr/local/lib/python2.7/site-packages/f5/bigip/__init__.py", line 114, in post_configuration_setup
   self._get_tmos_version()
 File "/usr/local/lib/python2.7/site-packages/f5/bigip/__init__.py", line 120, in _get_tmos_version
   signal.signal(SIGALRM, timeout_handler)
ValueError: signal only works in main thread

I put my code in Django views to get results from my GTM. It only works when I pass --noload --nothreading to Django runserver.

Django:

django-admin runserver

uwsgi:

uwsgi --ini uwsgi-docker.ini
