Speaking of which, it occurred to me a little while ago that
persistent connections between the http proxy and the website,
through Tor, can have an impact on anonymity.

If the user is figuring they're rotating their connections over different
Tor circuits over time (after all, they're clicking at different times,
right?), but polipo is holding open the same persistent connection,
then this changes things.

Is it documented anywhere how Polipo does its keepalives and timeouts
for persistent connections?

Fun fun,
