Not sure why. FWIW,

Well, this is just it.
# mount -t nfs4 -s -o sec=krb5i,rw,intr,rsize=8192,wsize=8192 linux:/home/share /mnt/test
on the client does not result in any NFS4 traffic between the client and
the server. In fact if I ^C the above mount and issue it again, I don't
get another gss/svcgssd upcall. Is there some kind of caching going on?
How can I invalidate the cache? Probably it's moot though given that
this sequence of events is not resulting in any NFS4 traffic anyway.
This was all working before last night, then all of a sudden, it
stopped. Nothing remarkable happened at the time that
could/should/would have caused this silliness. ~sigh~
