Bug 638773 - permissions too loose on pid and lock files
    
    https://bugzilla.redhat.com/show_bug.cgi?id=638773
    
    Description: This patch changes the permissions of the pid and
    lock files to be writable only by the owner (0644).  They should
    remain readable by all since they may serve in an advisory role
    to other processes that need to determine if it's running.
