It's better than nothing, though, and will unwedge Emacs in many situations. But if we had this facility (i.e., a way to make Emacs call some function after `C-g'-ing a lot during redisplay), then we can start experimenting -- and users can, too. So I think having a `break-during-redisplay-function' variable that specifies something to be called in these situations would allow some possible progress in this area. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
