/**
 * System_Daemon Example Code
 *
 * If you run this code successfully, a daemon will be spawned
 * but unless have already generated the init.d script, you have
 * no real way of killing it yet.
 *
 * In this case wait 3 runs, which is the maximum for this example.
 *
 *
 * In panic situations, you can always kill you daemon by typing
 *
 * killall -9 logparser.php
 * OR:
 * killall -9 php
