Comment (by cypherpunks):

 {{{
  if (or_conn->chan) {
 }}}
 Why need this check? If it's NULL then code will crash later anyway:
 {{{
 if (channel_is_bad_for_new_circs(TLS_CHAN_TO_BASE(or_conn->chan)) &&
 }}}


 {{{
 timestamp_last_had_circuits = chan->timestamp_last_had_circuits;
 }}}
 Happens twice. Why?


 {{{
 time_t timestamp_last_had_circuits = now;
 }}}
 Why inits not to zero? Why need to init?
