31    /**
32     * Below are a few static members of the LSCPServer class.
33     * The big assumption here is that LSCPServer is going to remain a singleton.
34     * These members are used to support client connections.
35     * Class handles multiple connections at the same time using select() and non-blocking recv()
36     * Commands are processed by a single LSCPServer thread.
37     * Notifications are delivered either by the thread that originated them
38     * or (if the resultset is currently in progress) by the LSCPServer thread
39     * after the resultset was sent out.
40     * This makes sure that resultsets can not be interrupted by notifications.
41     * This also makes sure that the thread sending notification is not blocked
42     * by the LSCPServer thread.
