BTW, rerunning your test as:

ping remote_ip_over_bonding_interface &
while 1; do
    echo -n "Downing interface..."
    ifdown bond0
    echo "done."
    sleep 1
    echo -n "Bringing interface up..."
    ifup bond0
    echo "done."
done

will allow you to more precisely identify whether the failure is during
the down or the up of the interface.
