What was not obvious was how just disabling interrupts was enough to
serialize the data. Jim's reference to Bind Break clarified that.
IBM has carefully worked out serialization rules for its own code; if
the customer messes with protected data, it's the customer's
responsibility to understand and follow the rules. I'd hardly call it
unilateral if IBM code changes something after properly serializing
it.
