Note: this is not really a normal SubprocessTransport. Although it implements the entire API of asyncio.SubprocessTransport, it is not designed to be used with asyncio.SubprocessProtocol objects. Instead, it pair with normal Protocol objects which also implement the SubprocessProtocol defined in this module (which only has a process_exited() method). Whatever the protocol writes is sent to stdin, and whatever comes from stdout is given to the Protocol via the .data_received() function. If stderr is configured as a pipe, the transport will separately collect data from it, making it available via the .get_stderr() method.
