Hi Tom,

I recall mentioning in Ohio, XCB doesn't have a private view of client callback state.  I'm unsure it's a good tradeoff to serialize XCB messages for "reliable delivery."  You would be changing the goal from "consistency is preserved" to "clients don't need to update their cache" on failover--at potentially very high cost, no?
