These days, advisory file locks (fcntl with F_GETLK and F_SETLK) should be
reliable enough over NFS (and on local file systems) on practical GNU and
GNU-like machines, and should be able to do everything that Emacs's symlink
lock files do.  (This wasn't true way back when the symlink scheme was
originally introduced.)  If we used advisory file locks, I daresay we
could get rid of those symlinks.
