Correct or incorrect, it doesn't allow me to do what I want to do.  Here
is my use case:  I want to sort the threads in my summary buffer,
post-gathering, by the date of the most recent article in the thread.
If threads (not the articles in threads) are sorted before they are
gathered, this seems less than possible.
