I definitely have it as a separate patch, and plan to commit it as
such. But I'm doubtful about backpatching it - without the controlled
sorting & flushing the impact isn't *that* big (i.e. not a factor of
5-10), and it could also cause performance regressions. We could later
redecide, but I'd rather focus on working on master.
