    Wraps a subprocess running ProxyCommand-driven programs.

    This class implements a the socket-like interface needed by the
    `.Transport` and `.Packetizer` classes. Using this class instead of a
    regular socket makes it possible to talk with a Popen'd command that will
    proxy traffic between the client and a server hosted in another machine.

    Instances of this class may be used as context managers.
