 Replying to [ticket:24022 teor]:
 > In #21394, we discovered that Tor clients sometimes retry the same exit,
 even when it is timing out.
 > Can we retry fewer times, but still have an acceptable risk of clients
 encountering a bad exit?

 Is that true? I hadn't concluded that from the data, but I'm not familiar
 with the code. Does it return to the same exit more than would be expected
 by a random exit selection?
