If the output actually shows up in the *inferior-lisp* buffer then the
easiest fix is:  M-x slime-redirect-inferior-output 
This is an Emacs-side only solution and doesn't involve the Lisp-side.

On the Lisp-side you can set SWANK:*GLOBALLY-REDIRECT-IO* in your
~/.swank.lisp.  That should be documented in the manual.

The stream to Emacs can be obtained with 
    (swank::connnection.user-io (swank::default-connection)) 
Perhaps you can to use that for your own tricks, e.g. with
mp:process-interrupt.
