------------------------------+--------------------------------
 I'm running Tor Browser 7.0.1 with tor 0.3.0.8.

 My guard slowed down significantly in the past week.
 It became very hard to get pages to load completely, although sometimes
 partial data was returned.

 I expect that after a lot of failures to connect to an exit (there are
 hundreds in my logs) tor would at least try another guard.

 But it didn't, and there is no easy way for me to tell it to try another
 guard. (New Circuit only changes middle and exit, the state file isn't
 reloaded on HUP #22662, and I didn't try New Identity, but NEWNYM is not
 documented to reset guards).

 Maybe making it hard to change guards is a feature, but if it is, we need
 to either use more than 1 guard (linkability implications), or give up on
 a slow guard.
