Or suppress file name handlers if the REMOTE arg is nil? Like

  (defun load-library (library)

--8<---------------cut here---------------end--------------->8---

Alternatively, we could just suppress Tramp:

!     (locate-file command exec-path exec-suffixes 1)))

  (defun load-library (library)
    "Load the Emacs Lisp library named LIBRARY.

!     (let (tramp-mode)
!       (locate-file command exec-path exec-suffixes 1))))

  (defun load-library (library)
    "Load the Emacs Lisp library named LIBRARY.
--8<---------------cut here---------------end--------------->8---

But in this case, other remote default directories would do the same
harm. Think about `url-handler-mode', for example.

Best regards, Michael.
