You must have missed my messages.  I did this several times and reported
that a simple call to add_keyboard_wait_descriptor was not the
solution.  I've tested on Mac OS 10.4 and 10.5.

After trying the Cocoa port, it's actually much better than the Carbon
port, and Carbon is deprecated on MacOS according to Apple (10.5
compilations report deprecated symbols for many Carbon functions).  I
think merging the Cocoa port would be a good thing.  Unfortunately it
doesn't help those who want to track CVS with the Emacs build today, and
I don't know how hard it will be.  Adrian Robert, the maintainer of the
Cocoa port at http://emacs-app.sourceforge.net/, is CCed here in case he
wants to give his opinion.
