 You have to remember that the args. you're passing to the program
 is on the stack, and while I can see the kernel folks being OK with
 a 10MB stack on 64bit archs., I don't think they'll ever go for a
 1GB stack just to carry program arguments. There are other methods
 to do that. Like the `-f file' option in grep where you can supply
 an arbitrary amount of pattern data.

 Out of curiosity: what value of ARG_MAX would make you happy? :)
