/**
 * This {@link MemcachedBackupSessionManager} can be used for debugging session
 * <em>deserialization</em> - to see if serialized session data actually can be
 * deserialized. Session data is serialized at the end of the request as normal (stored
 * in a simple map), and deserialized when a following request is asking for the session.
 * The deserialization is done like this (instead of directly at the end of the request
 * when it is serialized) to perform deserialization at the same point in the lifecycle
 * as it would happen in the real failover case (there might be difference in respect
 * to initialized ThreadLocals or other stuff).
 * <p>
 * The memcached configuration (<code>memcachedNodes</code>, <code>failoverNode</code>) is
 * not used to create a memcached client, so serialized session data will <strong>not</strong>
 * be sent to memcached - and therefore no running memcacheds are required. Though, the
 * <code>memcachedNodes</code> attribute is still required (use some dummy values).
 * </p>
