41 * Below are a few static members of the LSCPServer class.
42 * The big assumption here is that LSCPServer is going to remain a singleton.
43 * These members are used to support client connections.
44 * Class handles multiple connections at the same time using select() and non-blocking recv()
45 * Commands are processed by a single LSCPServer thread.
46 * Notifications are delivered either by the thread that originated them
47 * or (if the resultset is currently in progress) by the LSCPServer thread
48 * after the resultset was sent out.
49 * This makes sure that resultsets can not be interrupted by notifications.
50 * This also makes sure that the thread sending notification is not blocked
51 * by the LSCPServer thread.
