The things with zero link counts don't qualify as orphans.  The inodes get 
deleted, and then the vnodes get deleted, and then the directory entries 
get deleted (if any).

Well, except that IIRC, the current code doesn't actually _delete_ the 
files with zero link counts; it just completely ignores them.
