The problem with that approach is that it'd be horribly, horribly slow.

Yes it will be :-)

Maybe you could insert a DESTROY method into the targeted object, possibly aliasing any existing ones, and do the cleanup there?

Something like: 

if (ClassName->can('DESTROY') {
   *ClassName::OLD_DESTROY = \&ClassName::DESTROY;
   *ClassName::DESTROY = sub { 
       cleanup_object($_[0]);
       goto &$_[0]->DESTROY;
   }
}
else {
   *ClassName::DESTROY = \&cleanup_object($_[0]);
}

Update: this will not get you the object id... hmmm...
