Hi Marc, Andy,

Forgive my late joining of this thread, and apologies if I'm missing 
anything...

How do you intend to handle the stable storage issue? It seems to me 
that to comply with the RFC's requirement that stable storage be used 
when a grace period is offered, there needs to be a Cluster-wide, 
always-consistent, stable-storage, available to all nodes. I imagine 
that a correct implementation of this isn't a trivial exercise... :)

best regards,
calum.
