    I don't understand this. Can you explain what you are doing at a slightly higher level?

    • I found things in memory, colored them by type, and rendered an image each time I executed an entersub or leavesub opcode.

      It seems to work much better for some work servers which are actually full of data and make more interesting pictures.

      • Oh, I see. So this is an animation of memory alloc/dealloc over the lifetime of the app? What are the zones? Does Perl's malloc create arenas or something? Or are the zones different packages of blessed references?

        • Oh, duh... I guess "Internals::DumpArenas" implies pretty clearly that it's a map of arenas.

          • No, it's kind of roughly perl level structures. Like "this stash is really large" or "wow, will you look at the size of that string?!"
