Here's more. I seem to be getting stale NFS handle replies on the NFS-V3
commits and writes.
I am guessing that the problem is due, somehow, to install's writing or
renaming over of the original file, probably after stat'ing the original
file.
doing a mount -u -o acdirmin=0,acdirmax=0,acregmin=0,acregmax=0 ...
on my / and /usr NFS mounts does not fix the problem.
I am not ripping these files up from under the client .. the client
is the only machine messing with these files.

: It seems to be repreating the same NFS I/O over the network over and
: over again as far as I can tell. It is very odd.

: The network stays in saturation ( at 8 MBytes/sec ) until I kill -STOP
