Fascinating. It's certainly related. I tried this:

(setq compilation-error-regexp-alist nil)
(setq compilation-error-regexp-alist-alist nil)

Which reduced the delay significantly. The minibuffer flickers a bit
while displaying the "fontifying" message, but this made things usable
again. Thanks :)

Is there an easy way to prevent SLIME compilation messages from getting
fontified using those regexps at all? I'm hoping for a lighter-weight
solution than just clobbering these variables.

None, actually. The compilation buffer just says "0 compiler notes:".

Not at all. 5-10 characters, all ASCII letters.
