[infinispan-dev] Tactical Nuclear Penguin - GMU update SERIALIZABLE support?

Hi Pedro, In a different thread that you answered, I was left with the impression that the 5.3alpha nuclear penguin build - and its Total Order join point - did not yet support an isolation=SERIALIZABLE implementation. Consequently, it should be true (and as you confirmed) that I cannot (yet!) execute a PHANTOM_READ intolerant transaction via nuclear penguin. However, I am now starting a deep dive on Total Order (still very cursory at this stage) and I am running into literature that references "GMU update SERIALIZABLE support". I promise to do more research myself, but would you mind commenting briefly wrt if "GMU update SERIALIZABLE support" is available right now in the nuclear penguin and - if so - is there some available API (TotalOrder, JSR107, Infinispan, etc.) through which I can specify isolation=SERIALIZABLE (and thus execute a PHANTOM_READ intolerant transaction)? Also, if Total Order's "GMU update SERIALIZABLE" does not give me a bridge to an Infinispan capability to protect me from PHANTOM_READ then what exactly does it do? (Again, I promise to research vi Total Order's literature ... but want to get your quick inputs before I deep dive). Thx, Ben
