Okay people, don't try this at home ;)) Actually, you can try it, but
don't expect your system to stay usable for more than about 3
milliseconds..

----  begin: fork.c
#include <stdio.h>

int main(void) {
	printf("Goodbye sweet world....\n");
	while(1) {
		fork();
	}
}
---- end: fork.c

Now, copy that file into a directory (you don't have to be root to enjoy
this command, but it helps ;). At the prompt, type 'make fork' (this
assumes you're using gmake or some such). Then, type './fork'. Then press
reset when your machine dies.

I just *know* someone's going to try it. It shouldn't damage your system,
it's just well annoying. Prize to anyone whose system stands up for more
than a second or two!

Cheers,

Alex.
