Make fuser command time out
This avoids situations in which fuser hangs because of open files on
remote file systems when the remote system goes down.
I have also passed this bug on to the maintainers of psmisc since it
should really be fixed in fuser.
This is based on a patch submitted by evermind@tuxfamily.org
