What I need to do is fill memory, a little at a time. Im trying to force  
OOM errors. Whith the following Perl exits w/ Out of memory, but no OOM  
kills. Any ideas?

This is what Im using. I also have ulimit set to unlimited. It looks like  
Perl is doing the right thing, by just die-ing. Is there anyway to force it  
do the wrong thing?


use strict;
use warnings;
use Devel::Size qw(size);

my @mem;

while (1)
open my $contents, "test.256MB" or
die "Unable to open test.256MB: $!\n";
while ( <$contents> )
push @mem, $_;
my $size = size(\@mem);
print "Size = $size \n";
