I actually agree with you.

In my opinion, "*use-dedicated-output-stream* = t" is (and always was)
fundamentally flawed because you cannot guarantee anything about the
timing of the two streams (the dedicated stream and the slime event
stream).  

(That's why slime-repl-insert-prompt has included a timer kludge to
hide the race for a long time -- since revision 1.179 from
2004-01-15.)

I don't mind if this mode of output ("*use-dedicated-output-stream* =
t") is removed from SLIME.  As I said, I don't use it myself.

However, there were or are users who are interested in using
"*use-dedicated-output-stream* = t" because of performance
considerations.  I am trying to fix it for the benefit of those users.
