Hm, but since flushing a important COMMIT to the slave(s) will also need to flush all previous (potentially
unimportant)COMMITs to the slave(s), isn't there a substantial chance of priority-inversion type problems there?
Then again, if asynchronous_commit proved to be effective than so will this probably, so maybe my fear is unjustified.
