Add warning related to Identity correlation through circuit sharing
As long as #3455 (moved) and Tor 0.2.3 isn't ready, I recommend to add on https://www.torproject.org/download/download-easy.html.en a warning about Identity correlation through circuit sharing. Reference with problem description. [1] [2] [3] [4] [5]
I don't think many people are aware of the issue.
When you google you'll see, that people recommend, in order to torify various applications, to socksify using port 9050. Stream isolation, multiple SocksPorts and identity correlation are discussed nowhere.
And if those people mix different goals (let's say, hide location from chat server, registered with real name; and anonymous posting) or use multiple applications at once, they don't only theoretically risk their anonymity.
