The XEmacs developers told me 10 years ago that XEmacs used an inside-out structure, where Xt implements the event loop and calls Emacs to handle each events. That unnatural structure makes it impossible to write your own loop in Lisp. I rejected it. They told me that it was impossible to handle Xt with a natural structure, where the event loop uses the toolkit as a subroutine, but we did it. (Actually I think Paul Reilly did it.) I will not accept that unnatural structure now, any more than I did 10 years ago. However, I won't reject all possible changes in the event loop. It might be useful to rewrite the event loop in Lisp (keeping its present natural structure).
