To clarify: if only one server answers, the client will select that
server for future renewals. If two servers answer, the client will
still select one server, but the method of selection is poorly
defined...most clients select the first answer they receive. Since
one server or the other will generally 'always' win millisecond
battles such as this, load is not divided, but rather heaped on one
of the two systems.
