I suspect this happens while SLIME tries to interpret CMUCL's compiler notes but I currently have no idea how to debug this.
That or during pretty printing the event in the event log buffer. Can you try to disable slime-log-events? When I compile CL-PPCRE, with logging disabled, I get 396 notes; annotating and listing compiler notes requires about 10 seconds.
