Looks clean enough - only question I have is do we need a separate
'suspend block' or can latency do it -suspend is a very very high latency
event. I guess the suspend block is clearer in intent than abusing latency
but I do wonder if the actual suspend path should also check latency
constraints too. If I've asked for 5mS latency then suspend is a wrong
choice!
