That sounds encouraging, as a start. Could you start a new thread about all that, with all the authors of this original code in CC at least? Hiding such a large refactoring on a thread for the CRC failure would not help in terms of attracting the attention this requires in terms of reviews. You could also add me in CC if you wish. As far as I recall, we rely on the registered buffer at replay to lift a bit the lock restrictions for concurrency purposes, but that's pretty specialized in itself. Thanks, -- Michael
