I applied your patch (as mentioned above), and reverted
mac_unicode_keystroke_event in macterm.c to previously correct version,
and edited frame.c as below:
,----
| #ifdef USE_FONT_BACKEND
|   /* Give chance to each font driver to free a frame specific data.  */
|   font_update_drivers (f, Qnil);
| #endif        /* USE_FONT_BACKEND */
`----

then 
./configure --enable-carbon-app
export LIBS=-lresolv (to solve Undefined symbols: _res_init_9)
make bootstrap

I got a successful build of emacs-unicode-2 branch (latest cvs), but
key.mouse respond is still slow and unusable.

But I DO FEEL it's not slow as before. Just still unusably slow.

You said this solved the problem for TRUNK. I just wonder why it does
not work for unicode-2 branch. I read discussions about this problem,
and seems the conclusion is the problem is the same for TRUNK and
unicode-2 branch. (same reason, and I suppose same solution.)
