Why XML for data serialization? Do you need human readable cache storage? If not you could use Storable instead of XML::Simple.

Morever you could use Cache::Cache to handle caching. This module provides quite high level API for data cache (and AFAIK it uses Storable to serialize/deserialize data).

I've rewrote you example using Cache::Cache: 

# init cache object at the begining of the program
my $CACHE = new Cache::FileCache( );

.....
.....

#### Cut, subroutine from module

  foreach my $tid (@completed){
    $results{$tid} = $CACHE->get($tid);

    unless(defined $results{$tid}) {
      $results{$tid} = $self->Complex_Crap($tid);
      # data will expire in cache in 10 minutes
      $CACHE->set($tid => $results{$tid}, "10 minutes");
    }

  }

  $self->Results(\%results);
  
  return($self);

}

Update: Added example of Cache::Cache usage.
