In my tests, if one of the sort functions is
gnus-thread-sort-by-most-recent-date, then the above takes almost as
long as sorting all of the children too, since it needs to convert
*all* time strings to emacs times, and that dominates.

As you pointed out, the real thing to investigate is the rest of
the time taken for summary buffer generation.  Any takers?
