Why does my progarm leak?

It's written in FIOC which is supposed to manage memory for me but it kind of doesn't. All my program does is scrape a website, iterate over an arrays I build from the data I got and download a few things but after a while it grows to over 1000mb.

Fucking FIOC.

wouldn't it be hilarious if the threadstopper made and discussed threads though, huh guys?
