In this case it was just output to the repl. I disabled all repl text

Then how about making it easier for alternative implementations to be
used instead of the one that is provided with slime?
SLIME history is one example of idiosyncratic behaviour which was
introduced which has no parallel in any emacs application I've seen.
The implementation you provided is OK, and may be good for first time
users but I imagine the behaviour gets in the way of using SLIME
effectively for one already used to or proficient enough with Emacs to
expect things to adhere to certain UI "standards"
[*Completion* window handling and restoring window configuration is
another component that should be factored out. The assumptions made in
implementing this code do not cover most cases I face personally all
Speaking as a longterm and heavy user of slime, the other aspects that
were recently overhauled like the Inspector, the debugger,
output-display routines have also affected productivity: In the past I
was able to whack them into a shape that helped me program lisp
smoothly. Getting back the behaviour I want has is getting harder. As a
general observation: Instead of the factoring out of these components
I've seen tighter coupling which makes implementing alternative
behaviours harder and even harder to maintain local modifications when
