This is apparently an artifact of the Network Appliance (NFS-mounted)
filesystem. Here are the results of:

    for i in {64..66}; do
    echo "\n$i"
    dd if=/dev/zero of=testfile count=1 bs=$i
    ls -l testfile
    /usr/bin/du -a testfile;du -a -B 512 testfile
    done

When I run that same test on a local fs, here's what I see:

64
1+0 records in
1+0 records out
-rw-r--r--    1 shelton  vobgrp         64 Mar 11 14:07 testfile
