 * <ul>

 *     <li>One or more Lock Requester</li>

 * The general strategy is that the Lock Holder keeps locks open as long as there is no Lock Requester. This is,
 * because each lock open/close action requires File I/O which is expensive.
 * <p>
 * The Lock Owner will inform this contention handler that it holds the lock via {@link #start(long, Consumer)}.
