Description:
 async def process_message(self, message, wait=True):
 """Process a message to see if it wakes any waiters. This will check waiters registered to see if they match the given message. If so, they are awoken and passed the message. All matching waiters will be woken. This method returns False if the message matched no waiters so it was ignored. Normally you want to use wait=True (the default behavior) to guarantee that all callbacks have finished before this method returns. However, sometimes that can cause a deadlock if those callbacks would themselves invoke behavior that requires whatever is waiting for this method to be alive. In that case you can pass wait=False to ensure that the caller of this method does not block. Args: message (dict or object):
 The message that we should process wait (bool):
 Whether to block until all callbacks have finished or to return once the callbacks have been launched. Returns: bool: True if at least one waiter matched, otherwise False. """
