 I started my Tor Browser, and told it to use snowflake, and it did. Then I
 changed my mind and told it to stop using snowflake. Now, apparently
 there's a bug in Tor where Tor is supposed to kill snowflake-client when
 there are no more bridge lines in my torrc that want to use it. But
 ignoring that Tor bug, snowflake-client should also be defensive for me.
 Right now it is touching the broker every 10 seconds, looking for a
 snowflake, even though it is getting no requests. That can't be good for
 scalability or for the broker or for the users.
