"""
A simple watchdog for long running processes which may stall for some reason or
another.

If the main thread hasn't logged progress (by updating
``self.last_progress_time``) in WATCHDOG_HARD_KILL_TIMEOUT, the watchdog
thread will log an error containing the stack trace of all currently running
threads then use ``kill -9`` to kill the main process.

Assumes that a process monitor like supervisor or systemd will then restart

1. Put these files in yourapp/testing/
2. Install:
   • django-nose: https://django-nose.readthedocs.org/en/latest/installation.html
   • model_mommy: pip install model-mommy
3. Run tests with python manage.py test, or test specific files or directories with python manage.py test myapp/tests/test_models.py

3. Test cases which use the database must subclass MyAppTestCase, but other test can use test functions, generators, and everything else supported by nose: https://nose.readthedocs.org/en/latest/writing_tests.html
