Compiled templates are cached by default; to turn off child process will have its own IOLoop, so it is important that nothing touches the global IOLoop instance (even indirectly) before the fork.

When we receive requests, we iterate over the list in order and instantiate an instance of the first request class whose regexp matches the request path. The request class can be specified
