If there is an embarrassing-pause, then using a non-incremental copying collector won't help anyway. OTOH XEmacs has an incremental mark and sweep collector so Emacs should be able to remove the embarrassing-pause without copying. But I never looked at the respective codes of XEmacs and SpiderMonkey so maybe I'm missing something. martin
