I've just tested the patch with cvs head and it seems to work for me. I 
don't know how global io redirection was broken back then. Once thing I 
had to change in the process to reproduce is to add a (swank::init).

Detailed process to reproduce:
1. start an sbcl
2. (require 'asdf)
    (asdf:oos 'asdf:load-op 'swank)
    (setq swank:*globally-redirect-io* t)
    (setq swank:*global-debugger* t)
    (setf swank:*use-dedicated-output-stream* nil)
    (swank:create-server :dont-close t :port 4007)
    (swank::init)
3. connect from slime
4. from a buffer eval
  (loop 
   (sleep 5)
   (print 'hello *trace-output*)
   (force-output *trace-output*))
5. disconnect
[At this point output should be going to the terminal where sbcl was 
started which is the case when the above snippet is wrapped in 
(sb-thread:make-thread (lambda () ...))). Instead it goes to nowhere.]
6. slime-connect again
7. observe that nobody says hello anymore
