So, with the util-linux mount: if you have a directory "proc" that you've 
mounted something on, and also have a "proc" entry in /etc/fstab, the first 
time you umount it the local directory is unmounted, but the second time you 
unmount it, it complains that /proc is in use.

Different behavior based not on whether the directory at that relative path 
exists, but whether or not there's something mounted on it.

I'm not quite sure what the correct behavior is here, but I know that whatever 
it is my current umount isn't implementing it yet...
