This seems to work very well, even without byte-compiling the code.
Thank you very much for this. I'll send it off to the slime guys so
they can incorporate this code into slime.
As I say, I haven’t used slime much, and from looking a bit closer at the
slime code I can imagine my change being irritatingly slow to update
modelines in buffers that have just been displayed, after having been hidden
for some time. If you notice this, please give the below a shot; as well as
updating the modeline with each slime event received, it’ll update the
modeline every time XEmacs has nothing to do (that is, you’ve stopped typing
for five seconds, or whatever.) The older version of the recompute function
was a little readier to force a modeline update, which is not ideal if the
function is to be called from pre-idle-hook.

(symbol-value-in-buffer 'slime-popup-buffer-mode object))
