am I to young ?

When I first read this, I figured a call to panic() would likely bring down the system or set it in motion to abort before the frag explodes . Maaaybe I've just lived in a world where the Blue Screen Of Death (BSOD, a Microsoft copyright) is prevelent a little to long. The idea that it calls update("which I have yet to disect"), prints an error message and calls the kernels idle() loop times infinty is neat. Rather then bringing the system to a screeching halt right then and there. At first glance I would've expected it to take down the system right bam'n'slam now.

/*
 * Panic is called on unresolvable
 * fatal errors.
 * It syncs, prints "panic: mesg" and
 * then loops.
 */
panic(s)
char *s;
{
        panicstr = s;
        update();
        printf("panic: %s\n", s);
        for(;;)
                idle();
}

Of course from the fine book for study. It seems the only way out of a panic() attack is a restart any way, but its not an instant 'crash, have a nice foo&ing day, rebooting now sucker' kind of thing. Which interestingly a lot of times my Windows machines have gone down, *cough*. Its kind of been to the BSOD what the expression 'Do not pass go, do not collect $200' is to monopoly. It dies, you get an error, but it kills itself before you get to read it. Then tells you it was *probably* a driver issue lol.
