So far this is where I have got to.

In my timeout using callLater, I call d._canceller().

This calls _connectionLost_WAITING which is partly what I would expect. But it does not call _canceller_WAITING which I would have expected as well.

The function at d._canceller would appear to be cancelConnection so I can see why it would go to loseConnection right away. But I have not found where cancelConnection resides yet.

The _connectLost_WAITING then calls disconnectParser and finally does the errback with ResponseFailed and the connection is dropped cleanly.

The fact that _canceller_WAITING is not called makes me think I am making the wrong call on the request deferred when I use d._canceller(), but I have not seen anything else I can call.

Also d._canceller requires a parameter. And I can pass it anything and it seems to not make use of any argument I pass in. I have used d the deferred, None, 'TRANSMITTING' the string all with exactly the same effect.

So it makes me think I am making the wrong call on the request deferred.

Does anyone know if I should be calling some other function.

Below is the result from a test run outputting various points the program runs through which might be helpful.
