 Sometimes when I start my tor client and it's been a while, it takes 2 or
 3 minutes to bootstrap. It seems to be getting stuck on the "asking for a
 consensus" phase, maybe because the guards listed in my state file are
 gone, or maybe because only one of them is gone but my Tor doesn't handle
 it well. I'm not sure.

 It would be neat for somebody to set up a chutney or shadow configuration
 that sets up various bootstrapping scenarios and then observes time-to-
 bootstrap for each. For examples, setting up scenarios where our
 configured guards are all down, or all down but one, or we're firewalled
 such that our tcp attempts don't get an immediate failure, or our guards
 are up but they don't have their dir info yet or they have dir info but
 it's old, or some of our guards are overloaded so they serve dir info very
 slowly.

 We could use this approach to find regressions, and also to discover
 corner cases where we have more bootstrapping delays than we ought to.

 I call it an intern project idea because it's bite-sized and reasonably
 self-contained.
