 /* The strategy: to lock a file FN, create a symlink .#FN in FN's
    directory, with link data `user@host.pid'.  This avoids a single
    mount (== failure) point for lock files.
 
    When the host in the lock data is the current host, we can check if
    the pid is valid with kill.

    Otherwise, we could look at a separate file that maps hostnames to
    reboot times to see if the remote pid can possibly be valid, since we

    virtually all such systems are probably single-user anyway, so it

    Similarly, we don't worry about a possible 14-character limit on
    file names, because those are all the same systems that don't have
    symlinks.

    This is compatible with the locking scheme used by Interleaf (which
    has contributed this implementation for Emacs), and was designed by
    Ethan Jacobson, Kimbo Mundy, and others.
