I seem to remember Hans Reiser making a credible suggestion years ago
when NFSv4 was still in draft.  It didn't fly, but I don't really
remember why.

The NFS server gets to either return a cookie like it currently does,
or sets a flag (or maybe returns a special cookie) which says 'just
use the name'.
A READDIR request contains either a cookie or a filename.  Either mean
"This identifies the last name I got from you, give me the next one".

Is there something that makes that interface problematic?
