     * new method to it called 'keepAlive'
     * The subscriber must also provide a "watchdogReset". watchdogReset will be called
     * if the subscriber failed to call keepAlive withing the timeout period.
     * @param subscriber
     * @param timeout
     * @return the numerical key associated with this subscriber
