43     * Class handles multiple connections at the same time using select() and non-blocking recv()
44     * Commands are processed by a single LSCPServer thread.

47     * after the resultset was sent out.
48     * This makes sure that resultsets can not be interrupted by notifications.

50     * by the LSCPServer thread.
