This is a 4.4 feature -- stackable mounts. There was a paper about it
in the Winter 1995 Usenix.

It's annoying, though, when I edit fstab and do mount -a, in which
case it remounts multiple instances of some of the file systems. It
perhaps should avoid mounting the _same_ file system twice on the same
mount point.
