You did not explain how your proposal will avoid dropping the transaction
throughput down to disk speed, whereas I have explained how my existing
design can be made to achieve enterprise-grade data safety.

As far as I can see, there is no way to do what you propose without
losing a couple of orders of magnitude of transaction response time
under normal running conditions.  If you can see a method that I cannot,
then I am all ears.  Until then... I just loved the earlier post to the
thread:

  "It is not the best way to travel faster than light.  It is just
  the only way".

I do not think you have set out to solve the same problem I have, which
is to attain the highest possible transaction throughput with enterprise
scale reliability.  If you would like to take my code and modify it to
work just as you wish it, then of course you are more than welcome.
