Here, I'm getting confused.

Let's imagine I'm running the following script though ModPerl::PerlRun or 
ModPerl::Registry:

use strict;
package mypack;
my $lexical;
our $global;
print lexical: '  . $lexical. ' # global: ' . $global;
$lexical= 2007;
$global = 2007;

This script would print:
lexical:  # global:
the first time it is run

and then:
lexical:  # global: 2007

So, this clearly shows that the global variables sticks in memory, while the 
lexical one doesn't.
So, I would imagine that after the script is run, space used by the lexical 
variable would be freed up.

Am I wrong?
