It depends on one's point of view.  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.

Yes, perhaps there should be a way to turn off the use of
regular files for locking on MS-Windows hosts.
