Rdma::AsynchIO holds the data channel for a connection (the connection channel is held by Rdma::Listener or Rdma::Connector depending on the role of the connection) There is no relationship per se to an IO thread: when the code comments refer to "the thread" of a connection what they more correctly mean is correctly serialised with respect to that thread so that only one piece of code manipulating it is running at once.
