You're the one making the decisions now, but if you stack mounts and one of 
the underlying mounts goes away, bad things happen anyway.  (This doesn't 
have to be "eject", this can be physically yanking a usb key.  Overmounting 
removable media is a darn stupid thing to do, and people who do it deserve 
what happens to them.)  And if eject doesn't do an umount then it doesn't 
work in the general case.

What does the non-busybox eject do in all these cases?  (Quite possibly 
ignores them.)
