Can somebody with access to an MS-Windows machine help me test the code
below?
Evaling this in *scratch* suffices. `unlock-buffer' should signal an
error. It does on POSIX-like systems. I'm 99% sure it will on
MS-Windows too, but I'd like to confirm, as well as see the specific
error thrown. Emacs 27 or 28 is fine.
(let* ((dir (file-name-as-directory
(make-temp-file "unlock-test" t)))
(name (concat dir "a"))
(lockname-as-directory (file-name-as-directory (concat dir ".#a")))
(spoiler-name (concat lockname-as-directory "spoiler")))
(unwind-protect
(progn
;; Create a file named DIR/.#a/spoiler, then attempt to unlock a
;; buffer named DIR/a. `unlock-buffer' should signal a file-error.
(make-directory lockname-as-directory)
(with-temp-file spoiler-name
(insert "Hello, World!"))
(with-temp-buffer
(set-buffer-modified-p t)
(let ((buffer-file-name name)
(buffer-file-truename name))
(unlock-buffer))))
(delete-directory dir t nil)))

Emacs 28 here: I also see Permission denied (i.e. EACCESS).

After the error, without exiting the backtrace: C-x C-c
Emacs asks `Save file "c:/Users/"...' I answer `n'. Then asks `Modifier
buffers exists; exit anyway?', I answer `yes'. Emacs hangs, 0% cpu use.
Had to kill it with the Windows Task Manager.
That doesn't happen if I exit the Bactrace buffer with `q'.
