The dispatcher also has a special response code of its own: CONNERR
indicates that the connection failed and the command has therefore been
- lost; the
+ lost. This is sent to all outstanding commands when a connection error is
+ encountered: rather than a token list, it is accompanied by an exception
+ object which is the cause of the disconnection, which may be `None' if the
+ disconnection is expected (e.g., the direct result of a user request).
