   8      Base server class that handles basic concepts like application instance
   9      creation/pooling, exception handling, and similar, for stateless protocols
  10      (i.e. ones without actual incoming connections to the process)
  11  
  12      Your code should override the handle() method, doing whatever it needs to,
  13      and calling get_or_create_application_instance with a unique `scope_id`
  14      and `scope` for the scope it wants to get.
  15  
  16      If an application instance is found with the same `scope_id`, you are
  17      given its input queue, otherwise one is made for you with the scope provided
  18      and you are given that fresh new input queue. Either way, you should do
  19      something like:
  20  
  21      input_queue = self.get_or_create_application_instance(
  22          "user-123456",
  23          {"type": "testprotocol", "user_id": "123456", "username": "andrew"},
  24      )
  25      input_queue.put_nowait(message)
  26  
  27      If you try and create an application instance and there are already
  28      `max_application` instances, the oldest/least recently used one will be
  29      reclaimed and shut down to make space.
  30  
  31      Application coroutines that error will be found periodically (every 100ms
  32      by default) and have their exceptions printed to the console. Override
  33      application_exception() if you want to do more when this happens.
  34  
  35      If you override run(), make sure you handle things like launching the
  36      application checker.
