Well, that was very fast for me, too:

CL-USER(9): (clim-listener:run-listener)
; cpu time (non-gc) 1,100 msec user, 10 msec system
; cpu time (gc)     340 msec user, 0 msec system
; cpu time (total)  1,440 msec user, 10 msec system
; real time  1,446 msec
; space allocation:
;  297,880 cons cells, 12,937,112 other bytes, 0 static bytes

I will check and see what's up with my MDP's state space that makes it
go out to lunch.

Sorry to be so dilatory.  Travel and the resulting email avalanche to
handle are going to keep me slow investigating this.
