You are making inconsistent requests. When the server tells your app
it's commited, it has flush the transaction log cache. If your
assertion about is real, you cannot wait for commit, so your
requirements are imposible to satisfy ( of course, you could run with
scissors, but that will loose data without hdd failure ).

I answered to Rob's question with more details regarding my app.
