Fellow slimers,
I have a (Lispworks) console image in which I load some files, then run a function which starts multiprocessing, e.g.
XOS> (load-server) ;;; hundreds of lines of stuff loading here...
XOS> (main-thread) .............DONE!
XOS>
I've set this console to be my LISP-PROGRAM, and M-x slime starts it all up fine.
After step 1, I can play around source files, compiling forms with C-c C-c.
After step 2, most interactions land me in this state:
;;; Compiling file /tmp/filerbPYBy.lisp ... ;;; Safety = 3, Speed = 1, Space = 1, Float = 1, Interruptible = 0 ;;; Compilation speed = 1, Debug = 2, Fixnum safety = 3 ;;; Source level debugging is on ;;; Source file recording is on ;;; Cross referencing is on ; Loading fasl file /tmp/filerbPYBy.ufsl 1

If I try to continue with the 2nd restart, to specify a value for SWANK::*BUFFER-PACKAGE*, no joy either:
CL-USER 6 : 1 > :c 2 (find-package :xos)

Any clues? Anything info I can provide to help debug this?
I think there are fewer problems if I _first_ start multiprocessing, _then_ create a swank-server, then use slime-connect from emacs. But that's not nearly as convenient as just typing M-x slime. :-)
