... which is just plain silly, IMHO. This sort of finegrained access
control belongs into ACLs -- instead of a flag "the file belongs to user X,
but it's append-only and X may not change that", the file should belong to
root and have an ACL "X may append to the file".

And *poof*, suddenly it's even more finegrained and doesn't require
"root" either.

This is a fine case for differentiating between flags-for-generic-struct-stat
and flags-in-a-fs-specific-stuff-union.
