Subject: [PATCH] b=12977 r=mjmac r=yujian

If anything inside the "while read; do ... done" loop (or it's callees)
reads from stdin (a very common thing to do) it will consume input meant
for the read since it's reading from stdin with ${CSV_FILE} being
redirected to stdin.  Read on another file descriptor to avoid this.
