A slow UI is very irritating for the user, and I see this from time to
time with customize so I believe it is important.  But maybe the
solution should be to separate the rendering of Emacs from the single
threaded lisp enginge -- many GUI programs separate the rendering or
view aspects from the controlling part of the program.  Perhaps
support for GTK gets you this?
