* Add a new asyncio.subprocess module * Add new create_subprocess_exec() and create_subprocess_shell() functions * The new asyncio.subprocess.SubprocessStreamProtocol creates stream readers for stdout and stderr and a stream writer for stdin. * The new asyncio.subprocess.Process class offers an API close to the subprocess.Popen class: - pid, returncode, stdin, stdout and stderr attributes - communicate(), wait(), send_signal(), terminate() and kill() methods * Remove STDIN (0), STDOUT (1) and STDERR (2) constants from base_subprocess and unix_events, to not be confused with the symbols with the same name of subprocess and asyncio.subprocess modules * _ProactorBasePipeTransport.get_write_buffer_size() now counts also the size of the pending write * _ProactorBaseWritePipeTransport._loop_writing() may now pause the protocol if the write buffer size is greater than the high water mark (64 KB by default)
