    constructing a listener stub configured to at least receive the response and comprising at least;

    a handling plan that at least includes a set of instructions for receiving the response; and

    a listener socket configured to at least receive a network communication from the second computing system;

    transferring the listener stub to a stub domain;

    suspending the guest computing system; and

    reclaiming at least a portion of the computer system memory from the guest computing system; and

    as a result of the listener stub receiving the response from the second computing system, at least;

    executing one or more of the instructions in the handling plan according to the response received;
