Here's the relevant part of the ChangeLog.  Look right to you?  Is it
safe for 21.4.5?

2001-06-08  Ben Wing  <ben@xemacs.org>

------ gc-in-window-procedure fixes ------

	* alloc.c:
	* alloc.c (struct post_gc_action):
	* alloc.c (register_post_gc_action):
	* alloc.c (run_post_gc_actions):

	Create "post-gc actions", to avoid those dreaded "GC during window
	procedure" problems.

	* event-msw.c:
	Abort, clean and simple, when GC in window procedure.  We want
	to flush these puppies out.

	* glyphs-msw.c (finalize_destroy_window):
	* glyphs-msw.c (mswindows_finalize_image_instance):

	* lisp.h:
	Declare register_post_gc_action().

	* scrollbar-msw.c:
	* scrollbar-msw.c (unshow_that_mofo):
	Use a post-gc action when unshowing scrollbar windows, if in gc.

	* redisplay.c (mark_redisplay):
	Add comment about the utter evilness of what's going down here.
