% therefore, no glue is inserted, and the space between the headline and
% the text is small, which looks bad.
%
+% Another complication is that the group might be very large. This can
+% cause the glue on the previous page to be unduly stretched, because it
+% does not have much material. In this case, it's better to add an
+% explicit \vfill so that the extra space is at the bottom. The
+% threshold for doing this is if the group is more than \vfilllimit
+% percent of a page (\vfilllimit can be changed inside of @tex).
