Just a thought... maybe try compiling emacs 23 without xft support (if
that is an option on a Mac).  You lose antialiasing; you gain font
control via ~/.Xdefaults, and probably much faster font rendering.

I have been noticing some pretty big bugs in emacs 23.  For instance,
if I want to customize some options, a *Customize Apropos* buffer gets
opened, but the contents do not end up there, but instead they get
written to whatever buffer I had on top at the time.  My point is that
the problem may be emacs 23, not slime.  Emacs 23 is certainly a
variable, at any rate.
