I think we have fast enough hardware that we can afford the space and time
costs of having a back pointer in each inode to the parent directory.  Or
if you want to be ambitious, multiple parents (for hard links and other
aliases).  Then you can find the file name and get the MIME type from the
extension.

By the way, in AGMSRAMFileSystem, I simplified it by storing the file name
in the inode - it's a file property, not a directory property.  After much
thought, the loss of the ability to have different file names for the same
file is the loss of a misfeature that only causes user pain.  If you want
another name for a file, use a symbolic link.
