Thanks - but that's not a theoretical problem (necessarily). I'm
interested in the protocol itself; Alan has been talking about an error
in the protocol which would lead to failure *even if the protocol were
implemented correctly*.

What does "Active/Active" mean? Presumably not the same as
"primary/primary", which would be a configuration error...
