Slime + SBCL warnings, expected?

21 Mar 2020

      I'm using Slime-20200319, Emacs 26 and SBCL 1.4.16 on Debian 10.

Are the following warnings, which I saw invoking M-x slime, expected?

Thanks

(progn (load "/home/np/.emacs.d/elpa/slime-20200319.1939/swank-loader.lisp"
:verbose t) (funcall (read-from-string "swank-loader:init") :from-emacs t)
(funcall (read-from-string "swank:start-server") "/tmp/slime.8323"))

This is SBCL 1.4.16.debian, an implementation of ANSI Common Lisp.
