Error in _sudden_disconnect

[sris]

_sudden_disconnect tries to access the parameter callbacks that's not currently being passed to it.

  File "x/brukva/client.py", line 336, in get
    self.execute_command('GET', callbacks, key)
  File "x/brukva/client.py", line 242, in execute_command
    self._sudden_disconnect()
  File "x/brukva/client.py", line 179, in _sudden_disconnect
    self.call_callbacks(callbacks, (ConnectionError("Socket closed on remote end"), None))
NameError: global name 'callbacks' is not defined

Should be fixed in 7847906.
Re-open if not.
