It's unlikely that q picks the wrong restart.  The restart is stored
in the global variable *sldb-quit-restart* with something like this: 

    (loop
      (with-simple-restart (abort "Return to SLIME's top level.")
        (let ((*sldb-quit-restart* (find-restart 'abort)))
          ...)))

And q essentially does:

  (let ((restart (find-restart *sldb-quit-restart*)))
    (cond (restart (invoke-restart restart))
          (t (error ...))))

This look quite robust to me.  The problem is probably some caused by
some other issue.
