AFAIK, it's because the Pickler object keeps a reference to each object so
that pointer-sharing works; if you write the same object multiple times,
you get multiple references to a single object, not multiple objects.

This means that the dictionaries aren't deleted while the Pickler object
lives.

It would seem that this issue could be avoided if pickle used weak
references, but there may be issues which I have overlooked.

At first I was just too lazy to visit stackoverflow and skipped this
posting. Then I thought: Why didn't you include the content, so people can
actually answer this question here? Therefore the only answer you got here
is utterly useless because the whole context is missing!

Then, something worse dawned upon me: Since stackoverflow is a "free" site,
their business model probably involves data mining or advertising, and since
you just posted a link to that site with the sole goal of getting people to
visit it, you have effectively (But I'm definitely not saying intentionally
and knowingly!) become a spammer.

I'm really not blaming you, but this is puzzling me and I'm not sure how to
react at the moment...

Cheers!
