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 Reported-by: evermind@tuxfamily.org X-Gentoo-Bug: 455458 X-Gentoo-Bug-URL: https://bugs.gentoo.org/show_bug.cgi?id=455458
