Yes, it's pretty frustrating when a parent mount in a mount hierarchy gets
hung up like that.  I usually run into it when the server for the
directory goes down.  I can't unmount it because the submounts keep it
EBUSY and pathnames to umount the submounts get hung up on the dead
parent.  Sadly, the only way out of this catch-22 is to reboot.
