@MikeBishop 
> I think the situation @kazuho is trying to describe is that, for whatever reason, the SETTINGS frame isn't transmitted until the sender has something _else_ to send on the control stream. Since that is required to come after SETTINGS, it finally sends SETTINGS then.

Yes, that is what this sentence tried to state. OTOH, I am somewhat negative against allowing such postponement, as @martinthomson says.

The contract should either be "SHOULD send" & "MUST NOT block on receipt" or "MUST send" & "SHOULD NOT block on receipt". At the moment, #2986 takes the latter approach.
