Under Linux you could walk the dentries and get a usable path at the
VFS layer.  There is already code that does this.

In fact, I was considering various ways to do something like dnotify
that would give full path information via a magic network socket or
something (exactly how it should work is still unclear to me,
different permissions along the path might mean you aren't entitled to
events you would otherwise get).
