Depending on what you are trying to do, you can hack your way around "Module Unloading".

...
## save data, ignore if you are archiving something already on disk
my $blah = $tmp_dir . $$ . '.tmp';
open( TMP, ">$blah" ) or die;
print TMP $data;
close( TMP );

## run another archiving script
unshift( @archive_args, $blah )
my $is_archived = system( $perl, $archiving_script, @archive_args );

## read archive, copy it, move it, unlink it, etc.
...
[download]

Like I said, it is a hack. There are several things to keep in mind, like security, data integrity, your app will "freeze" until the system call returns, and you are only freeing memory used by Archive::Zip( not memory used by the data itself ).

I hope this helps a little.
