I've attached a small patch to diagnose stale filehandle (error -116) problems.
Could you give this a try and report back the messages?

The patch to nfs2xdr.c has two unrelated parts -- one to fix the short readdir
replies, one to pad writes for "garbage args" problems. The second part has to
be manually enabled by uncommenting the define for NFS_PAD_WRITES. If you
uncommented the define, try commenting it out again and see if that changes the
symptoms.
Unfortunately I can't reproduce any of the problems you report here -- both
unfsd and knfsd work fine for me.
