Update: Ignore this! It is much slower.

This might work out a little faster if performance is a issue--which it usually is with genome related stuff. 

#! perl -slw
use strict;

my $re = '([^X]+)X*' . '(?:([^X]+)X*)?' x 100;
$re = qr[$re];

my $screen = "ATCGATCGXXXXXATCGATXXXACTGCTACGGTACXXXAATTATXGCGCGXXT";

$screen =~ $re;

print for @-[ 1 .. $#- ];
