 In Mike's future world where we allocate streams to different circuits
 based on their referer header (#3455), that means the number of circuits
 we make will be a function of our browsing behavior (e.g. number of tabs
 we interact with).

 How much can a local observer learn about the number of circuits we make
 based on seeing network traffic, and how much can that attacker deduce
 about our browsing activity based on number of circuits?

 Do the answers change when we consider an entry guard instead?
