Comment (by dgoulet):

 Replying to [comment:5 mcs]:
 > Specifically, I wonder if it will be safe for Tor Browser to assume the
 control port event will be sent before the browser receives a failure for
 the CONNECT, or at least to assume that will occur in most cases.

 Hmmm... Control port events, when they occur, are queued in a list and
 then an tor main loop event will send the queued events on the socket.

 So, if I'm not mistaken, you will get a connect failure _before_ you get
 the control port event because tor will return the SOCKS failure before
 that control port "empty queue" event is triggered.
