According to what I am reading in the fhs, /var/lock is not sharable between multiple systems. Also, the contents of the lock file is supposed to be the pid of the process that holds the lock [1]. Given that, a lock will automatically be invalid when you reboot, so it should be forgotten about on a reboot. William [1] http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES
