Bogdan Opanchuk 8efea0ccbb Break reference cycle created by default in Flask instances. ... Flask instances with static folders were creating a reference cycle via their "static" view function (which held a strong reference back to the Flask instance to call its `send_static_file` method). This prevented CPython from freeing the memory for a Flask instance when all external references to it were released. Now use a weakref for the back reference to avoid this.
