One other thought. Part of the reason GNU/POSIXish hosts use
symbolic links is that readlink, symlink and unlink
are atomic operations. They let Emacs atomically create
a lock, test whether a lock exists, and remove a lock. This
doesn't seem to be true of the new MS-Windows implementation,
which uses open+write+close to create a lock and open+read+close
to test whether a lock exists, neither of which is atomic.
Is there some way this can be done atomically on MS-Windows?
Are readlink, symlink, and unlink atomic on MS-Windows?
