This allows lockerd to process returns from hosts with aliased names.
** Support locking across multiple domains. [Daniel DeFolo]
*** Use fully qualified domain name instead of hostname. [Daniel DeFolo]
*** Destroy_unlock now only unlocks when the current pid matches the pid
that requested the lock, to prevent forked processes from unlocking
the lock. [Jeff Dutton]

*** Added pid=># parameter for setting PID to track. [Stephen Adkins]
*** Added lock_list() method. [by Anton Berezin]
**** Fix tests to start the servers automatically.

Optional. If running, allows for autounlocking across any hosts,
and for any generic application to determine if a PID exists on the
server's machine.
*** Added ping() method for determining if a server is up.
*** Added example init.d/lockerd file.
** Added autounlock switch to locks. This records the host
and pid which obtained the lock, and if that PID disappears
the lock is released to a new host. [Stephen Adkins]
*** Fixed bug which made lockerd --port option not work.
*** Allow colon separated hostnames for fallback hosting.
** Allow multiple lock names on lock requests,
and return the first one which becomes free. [Mike Lopresti]
** A zero timeout will disable timeouts. [James FitzGibbon]
** Changed default port to 'lockerd' which will look up the port
number in /etc/services. If not found defaults to old 1751.
*** Improved detection and recovery of daemon failures.
** Added support for Unix named sockets
