... but doing umount the same number of times you've done mount isn't ;-)

Actually, the more I'm looking at it, the more it seems that correct
solution is to consider mount as
        if (nothing mounted)
                mount
        else if (mounted is not busy)
                replace
        else
                fail
Makes sense for union-mounts too - normal mount is =, union is += ...
