     ppp changes the permissions to 640 on the device it is using, and
restores them when it exits.  If it exits abnormally (crash, kill -9,
etc) the permissions are not restored.  I have suspected that it does
not always restore them on a normal exit, but haven't been able to
prove that to my satisfaction.
