That works if you don't have a process blocked on IO to stale mount.
IME fuser -k and umount -f don't work on these; reboot is the fastest
way to clear it.
It gets particularly bad when you have a bunch of servers exporting
some FS's and nfs-mounting some others. Then you end up with dependency
loops where rebooting one server creates stale mounts on others.
Loads of fun.
But this is way OT.
