Wow! I, actually, thought about it, but I didn't expect it to work right
now, I would expect the umount to fail with EBUSY... But it does work!
Guys, it rocks! The only slight inconvenience - mount still shows

/tmp/blah/relative_path /desired_mountpoint (bind)

which is not necessarily informative. A better display would be, perhaps

<whatever>:relative_path /desired_mountpoint (bind)

in /proc/mounts also not quite true:

<whatever> /desired_mountpoint

One might want to improve those...

Thanks
