I could go along with something like this, though I don't want to
guarantee any specific schedule. It could be that a change (like
Brazil's) is not urgent and that later changes need some time to
percolate through the system, for example. With that in mind, I'll try
to generate other low-priority changes that are consequences of email to
this mailing list that haven't been acted on, or are other changes I've
been meaning to do. We might as well batch them in while we're putting
out the Brazil change.
