_populate() sets the populating attribute to prevent infinite recursion in
case a urlconf includes itself. The flag is a threadlocal to avoid a race
condition [1] where one thread sets the flag and another checks it, then
proceeds to access data that's supposed to be populated (e.g. _reverse_dict)
but isn't yet.
The potential still exists for a thread to set the threadlocal, then be
interrupted by a signal such as SIGALRM and raise before resetting the
threadlocal flag. In this scenario, subsequent calls to _populate() in the
same thread will short-circuit erroneously.
The bulk of the method was already wrapped in a try/finally in

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Thanks for checking it out. All documentation is in the "``docs``" directory and online at https://docs.djangoproject.com/en/stable/. If you're just getting started, here's how we recommend you read the docs: * First, read ``docs/intro/install.txt`` for instructions on installing Django. * Next, work through the tutorials in order (``docs/intro/tutorial01.txt``, ``docs/intro/tutorial02.txt``, etc.). * If you want to set up an actual deployment server, read ``docs/howto/deployment/index.txt`` for instructions. * You'll probably want to read through the topical guides (in ``docs/topics``) next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific problems, and check out the reference (``docs/ref``) for gory details. * See ``docs/README`` for instructions on building an HTML version of the docs. Docs are updated rigorously. If you find any problems in the docs, or think they should be clarified in any way, please take 30 seconds to fill out a ticket here: https://code.djangoproject.com/newticket To get more help: * Join the ``#django`` channel on irc.freenode.net. Lots of helpful people hang out there. Read the archives at https://botbot.me/freenode/django/. * Join the django-users mailing list, or read the archives, at https://groups.google.com/group/django-users. To contribute to Django: * Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for information about getting involved. To run Django's test suite: * Follow the instructions in the "Unit tests" section of ``docs/internals/contributing/writing-code/unit-tests.txt``, published online at https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests
