I've just tested this patch (after removing the bits which prevented
it from applying; they look like they belong to a fix for issue 1152.
:)  It has a dramatic effect in several cases: on one 26 page score
it's halved the compilation time to just over a minute.

On Haipeng's `Harmonious' score
(http://lists.gnu.org/archive/html/lilypond-user/2010-07/msg00122.html),
I get the following results (both optimized):

master: 3m40.766s
patched: 2m3.297s

Cheers,
Neil
