Thanks, I installed these, with one exception: I limited
gc-cons-threshold in doc/misc/Makefile.in to 50,000,000, not
most-positive-fixnum.  The slowdown in producing the Org manual as
result of that is negligible, and I didn't feel comfortable with
disabling GC altogether, as it caused the Emacs memory footprint go up
to 0.5GB.

These changes slash the conversion from 2.5 min to just 35 sec on my
system, with an unoptimized build of Emacs, which is a terrific
speedup.  Thanks!
