Description:
 def wait(self, timeout=None):
 """ Return the result, or throw the exception if result is a failure. It may take an unknown amount of time to return the result, so a timeout option is provided. If the given number of seconds pass with no result, a TimeoutError will be thrown. If a previous call timed out, additional calls to this function will still wait for a result and return it if available. If a result was returned or raised on one call, additional calls will return/raise the same result. """
