Just for fun I ran
#!/usr/bin/perl
$str = A x 500000;
while(1){
$str .= $str;
}
I watched it with top. It grew until it's memory usage was 965 M,
and was swapping, then it died with "Out of Memory". I'm guessing
as the 965 M tried to concantate the last time, it hit the 2 gig file
size limit? Since everything in linux is a file, I'm guessing when your
memory usage hits 2 gig, you stop?
