 get_lastcommentmodified() selects on comment_date_gmt <= $now.
 comment_data_gmt is not indexed, making this a slow query.  I don't see
 any reason for doing <= $now.  Comments can be edited to be in the future;
 however, future comments are not excluded from any other query.  They show
 in the comments loop.
