    Well, isn't there a way/tool to, from the main section of the script, find out which memory locations aren't accessible? Everything should be accessible (except for closures) and all of that can be pointed out. You can then read through the output, mark off which you know to be closures, and then you have your answer...

      If things weren't accessible, how would you find them? At least in pure Perl, this would be impossible. You could iterate over all the symbol tables, following references to reachable objects, but this wouldn't find things that had leaked.
        In pure Perl, yes. In XS, it should be possible to iterate through the entire region of memory and see if anything has a valid reference. Also (and I'm stretching my memory here), isn't there a way in C to find out all the malloc'ed areas? You could compare that with the list of all reachable objects and see if there's a discrepancy...
