/**
 * A kryo {@link Serializer} that creates a copy of the source map for writing object data.
 * 
 * This is useful for applications where objects/maps that are serialized
 * might be accessed by different threads. However, it only reduces the probability
 * of concurrent modification exceptions, as even during taking the copy the
 * map might be modified by another thread.
