Before, locking worked on GNU/Linux hosts. With the change, locking is no longer reliable on GNU/Linux hosts if an MS-Windows session is active or has crashed. So GNU/Linux users are worse off than before. MS-Windows users are better off of course, but we should strive for a solution that doesn't also make GNU/Linux users worse off. > A much more likely scenario is to see users complain/worry on > gnu.emacs.help about weird files appearing on their systems Yes, perhaps there should be a way to turn off the use of regular files for locking on MS-Windows hosts.
