91 * Use: Sets up a nonblocking connect job. The socket should already
92 * be bound if you care about that sort of thing. When the
93 * connection completes, the handler function is called with the
94 * connected socket as an argument. If the connect fails rather
95 * than completes, the socket is closed, and the handler is
96 * informed of this by being passed a negative file descriptor.
97 * In either case, the select job is then removed.
