            posix_kill($processors[$ix], SIGTERM);
        for($ix = count($processors) - 1; $ix >= WANT_PROCESSORS; $ix--)
            pcntl_waitpid($processors[$ix]);
    } elseif(count($processors) < WANT_PROCESSORS) {
        for($ix = count($processors); $ix < WANT_PROCESSORS; $ix++)
            spawn_processor();
    }
}

spawn_processors();

while($run) {
    $cycles++;
    if($reload) {
        $reload = false;
        kill_processors();
        spawn_processors();
    } else {
        check_processors();
    }
    usleep(150000);
}
kill_processors();
pcntl_wait();
