Namespace pollution / 2

Oooops, sorry, I hit "Send" accidentally before... here it is again:
--------------------------------------
Hi List,
I have a rather huge ASP application (a portal engine). Recently, I have 
seen some of the pages slowing down very much.

I have tracked down the problem to the following lines:
       my $dump = Devel::Symdump->rnew;
       my @classes = $dump->packages;          # All loaded packages
       my %list;
                                                                                                                            
       foreach my $class (@classes) {
               if (isa($class, 'COPE::Block::Base')) {        
                       $list{$class} = $class if ($class->isPage);
               }
       }

The problem is the @classes array contains thousands of packages. I put in some debugging and 
this is what is "polluting" here:

I have hundreds of packages(?) like this, all starting with
"/tmp/statedir/0d/0d2cbb902af8ec938b3aa2792f4c140247$MlDbM{ ..."
The question is: how are these artifacts generated? What is more likely: it is an MLDBM::Sync/Apache::ASP/mod_perl/etc. bug, of something is 
doing this in my application?

Thank you,
