 * The p2p-buffer for sockets to be processed. This circular buffer is
 * filled by the server thread and keeps sockets for the socket thread.

final class SocketBuffer  extends CircularBuffer<Socket>
 * The count of sockets to buffer.

 * This method will be called whenever the buffer overflows and an item
 * should be determined to be dropped. If none can be found, the new item
 * will be dropped. This method returns <code>true</code> if the specified
 * old item can be dropped and the new one can be buffered instead.
 * @param p_old_item    The old item to be maybe dropped.
 * @param p_new_item    The new item, which could possible replace the old
 *                      one.
 * @return  <code>true</code> if and only if the new item may replace the
 *          old one, <code>false</code> if the old item should be kept.

 * @param p_item  The item to be dropped from the buffer.
