I've tried that preference on my vm and it seems like it doesn't work at all. If I set it to 1 sometimes it will try to upload the first file on its own, but then after this one is done, inevitably it will upload the rest of the batch at once.

I think this is fixed, but I can't be sure.
Local uploads are deceptively fast, so the initial report (from "[gilles's] vm") may have just been a matter of perception.
In any case, the final form of the massive refactor *seems* like it has no way to exceed the configuration variable in question, so until we see reports to the contrary, I'm closing this.
