At the moment, callRemote dispatches to broker._sendMessage, which generates its own deferred with no canceller.
We should have a canceller which sends a message to the remote end, and a corresponding message handler that cancels the remote deferred, allowing for long-running callRemote's to be stopped.

Research direction
Start at broker._sendMessage and trace how callRemote creates its Deferred and how the remote message is handled. Define the cancellation message flow so the local canceller reaches the remote end and cancels the corresponding deferred; done means long-running callRemote operations can be stopped remotely.
