I guess what I am not 100% clear on is how these annotations affect the BPU. I.e. is it a static decision point or can the BPU still "learn" if the annotation is particularly wrong for a given workload? For the former, I think we should just remove this particular annotation (and there are others that need review). For the latter, this is obviously the right annotation we should be using in this particular case.

OK, if I just remove the likely() do you Ack it?
