where is "compute_status" defined ?

Whats purpose of status_stream_retry_timeout in code? Its just being passed but not used? Is client suppose to make use of this somehow? If so, how?

Whats purpose of status_stream_retry_timeout ? It just seems to be passed in event data. Is client side suppose to handle it in anyway?
