It used to be possible to stop slime from popping up the repl buffer (when evaluating forms from a file, say) with the following:

,---- ;; madhu 050219 (pop-up-windows nil) | ;; pop-up-windows | (defun slime-maybe-display-output-buffer-better-not (start end)) | (setq slime-show-last-output-function | 'slime-maybe-display-output-buffer-better-not) `----

This mechanism has been removed recently, How could I achieve the same effect in newer slime? i.e. ensure that slime does not pop up buffers during evaluation
