You can also use IOLoop.run_in_executor Thread-safety notes In general, methods on RequestHandler and elsewhere in Tornado are not thread-safe. In particular, methods such as write(), finish(), and flush() must only be called from the main thread version 3.2.2: The xsrf token will now be have a random mask applied in every request, which makes it safe to include the token in pages that are compressed.
