State-Changed-Why: 
I am unable to reproduce this on 7.0, but with all of the Giant
locking in 5.4 it was very plausible that was the cause
(i.e. everything fighting for Giant and starving NFS until the timer
fired).  Please let us know if it recurs on 6.x or 7.x.

P.S. The example fstab has -U for UDP mounts, I assume that was an
oversight (but tried both).
