I'll have some more data soon, but it's starting to look like the commit that
sent performance to hell was not my cd9fde325f, but Deri's 98b0c1db476
("Support UTF-16 Bookmarks.").

Maybe that commit was necessary, but I wonder.

I'll know more after this 20+ minute build of
"linux-man-pages-book-deri.groff" (my name for "LMB.prep") finishes.
