Actually they do run sequentially, but the minibuffer text is repainted
directly after the 'message' call, while the buffer text is only
repainted at the end.  Try this:

(progn (insert "side effect 1")
       (message "side effect 2 %s" (buffer-string))
       (sleep-for 10)
       (insert "side effect 3"))

or this:

(progn (insert "side effect 1")
       (message "side effect 2")
       (sleep-for 10)
       (insert "side effect 3"))
