[SECURITY] Fedora 22 Update: python-tornado-3.2.2-1.fc22

Tornado is an open source version of the scalable, non-blocking web server and tools. The framework is distinct from most mainstream web server frameworks (and certainly most Python frameworks) because it is non-blocking and reasonably fast. Because it is non-blocking and uses epoll, it can handle thousands of simultaneous standing connections, which means it is ideal for real-time web services.
