 > Now all authorities have `Bandwidth=20 Unmeasured=1`. I guess this is
 the reason why they are almost never selected for normal circuits. This
 could be done cleaner--as tor options which (1) disable client traffic
 (for usual circuits) at authority and (2) disable use of authority on
 clients when they create circuits.

 Sure, please open a ticket.

 > Requests of consensus, I suppose, just ignore `Bandwidth` option.

 When a tor client is bootstrapping, it does not have a consensus, so it
 does not know the bandwidth of the hard-coded authorities and fallback
 directory mirrors. It uses the hard-coded ratio, which selects fallbacks
 10x as much as authorities.

 When a tor client has a consensus, it uses the bandwidths in the consensus
 to choose directory guards. Then it chooses among those directory guards.

 > Yes, it should be either documented with proper warnings or disabled
 completely. Moreover, it has another bug: `ControlPort` can be specified
 more than once in `torrc`, and Tor will listen on all these addresses, but
 this behavior is not documented in `man torrc`. All options which can be
 specified more than once are marked with a sentence like (example of
 `SocksPort`):
 > > This directive can be specified multiple times to bind to multiple
 addresses/ports.
 > Should we create a separate ticket about `ControlPort`?

 Yes please.
