> deferred settlement and reconciliation We call this eventual consistency nowadays.

  This thread shows more about what people know (or don't know) about the CAP theorem than about two-phase commits.

  Settlement is somewhat different than the EC models you're used to. For one thing, a settlement may never occur and an unwind will be required. At least the EC systems I've dealt with where there application is responsible for resolving the conflict don't really have the concept of doing a chain-of-events unwind. My complaint here is that there actually are two data layers here with completely different semantics and the difficulties of 2PC are meaningfully relevant to the system-of-record layer, not so much the log layer (since enqueue into the log is not really problematic in the real world).
