When a command agent arrives on a remote node, it registers with the agent channel using its response id. And when a response is returned, the agent channel unregisters the agent. This registration is used by a user interrupt agent to locate the command agent being interrupted. On receipt of a user interrupt (^C): the to command sends a user interrupt agent to the remote command agent, the who command returns a partial result and the pause command cancels its timer.
